Selecting the right stainless steel finish for your application is very important. You are probably looking for a long lifespan, corrosion resistance and low maintenance needs. The right finishing is the way to guarantee that stainless steel will behave as expected.
However, the process can be somewhat confusing. There are different standards that offer their own designation for each type of stainless steel surface finish. Some manufacturers even create in-house standards to designate the surface finishes of their products.
To make it simpler for you, we recommend focusing on the most recognised standards around the world. For example, both DIN and ASTM standards are very common. Therefore, we are using these as our examples.
Lets start by comparing the DIN and ASTM finishes in a table format. This gives you a great overview of the possibilities using both standards. Well get into the details of each finish later in the article.
Mill finish is the basic supply condition for stainless steels, no matter whether they are cold or hot rolled. However, most of these steels require further finishing processes to meet the requirements of certain applications.
After the steel is hot rolled in the mill, it is then put through a heat treatment called annealing. Annealing consists of heating the steel and letting it cool down slowly to remove internal stress and reduce hardness. This makes it more ductile and workable.
After the annealing process, the 1D stainless steel is ready for the last step to achieve the designated finish pickling. This process consists of cleaning the surface with acid to remove the scales. Scales form during the previous processes, hot rolling and annealing.
1D stainless steel is sometimes used as the starting point for polished finishes. However, common applications of this stainless steel surface finish involve non-decorative purposes. Thus, the visual appearance is not always relevant. Some examples include:
As this steel is cold rolled rather than hot rolled, the surface finish is more refined. The annealing and pickling processes improve its characteristics in a similar way as with the 1D stainless steel. In this case, pickling is necessary because annealing is performed to remove stress and reduce the hardness resulting from cold rolling.
Similarly to the 1D surface finish, the 2D can be the starting point for polished finishes. It can also be used for some industrial and engineering needs with less critical aesthetics. Common applications for 2D stainless steels are:
Another cold rolled stainless steel where the process is similar to producing 2D. The difference is that there is an extra step in producing 2B stainless steel surface. That step is rolling it one final time with highly polished rolls known as bright rolls.
Due to its dull grey and not very reflective appearance, it is only used in architecture when uniformity of finish is not a requirement. Common applications for the 2B stainless steel finish include, but are not limited to:
Again, there is only a small difference with previously described surface finishes. In this case, we have the bright annealing process added. It consists of annealing the steel under oxygen-free conditions to protect it from oxidation and scaling.
The resulting stainless steel finish is capable of reflecting clear images. It is very smooth and less likely to harbour airborne contaminants and moisture compared to any other mill finishes. This easy-to-clean finish has a typical Ra between 0.050.1 micrometers.
This one is a little different to the rest of the mill finishes. Here, the metal is cold worked after the cold rolling process in order to obtain improved strength. The hardening is done by means of temper rolling on polished rolls. 6 different levels of strength are available depending on the yield strength, tensile strength and elongation.
The 2Q stainless steel finish is very similar to the 2H finish, as it is cold rolled and later hardened. The difference is that the 2Q is hardened and tempered in a protective atmosphere or descaled after heat treatment. Therefore, it is specifically used on martensitic steels which are the ones that respond to these treatments.
A few recommendations apply when selecting a stainless steel for your application. As a starting point, choose a mill finish that is the closest to the desired outcome. This way, the number of additional processes can be minimised.
However, there are standard finishes that are achieved by mechanically polishing and brushing the surface. This means that the surface will be processed by using abrasive materials that effectively cut the surface of the steel to a desirable degree.
The resulting surface finish for mechanically polished and brushed stainless steels will depend on different aspects. Those include the original surface (starting point), type and texture of the polishing belts and brushes, and the nature of the polishing process used.
Due to the process used, the resulting finish provides a rather coarse, unidirectional surface with low reflectivity. The surface roughness can be defined by the manufacturer and agreed with the customer upon request. Most manufacturers define the Ra up to 1 micrometer.
The starting points for these finishes are the same as the previous ones. But now the hot rolled or cold rolled steels are processed with polishing belts or brushes. Thus achieving a more refined surface compared to the 1G-2G surfaces.
However, the result is still unidirectional and not very reflective. The grade of the brush, polishing belt or surface roughness can be specified by the manufacturer. Typical average roughness is between 0.21.0 micrometers, although most manufacturers prefer to stay around 0.40.6 micrometers for the 1J 2J finishes.
The same starting point as the 1K 2K finishes. The last process in this case is polishing and buffing with soft cloth mops and special polishing compounds. This helps to achieve a bright polished finish.
The 1P 2P are non-directional, ultra-smooth and highly reflective finishes with a high degree of image clarity in the reflection. Typical Ra values for these stainless steels are below 0.1 micrometers.
Producing patterned stainless steel finishes includes pressing or rolling with patterned rolls. These operations result in an effectively stiffened sheet. As a result, this allows for thinner gauge cladding, a subsequent possible cost saving and overall weight reduction.
It usually starts with a 2B or 2R mill finish. So, the common processing involves cold rolling, heat treatment, and skin pass on roughened rolls. Sometimes, bright annealing or annealing and pickling can be performed.
The design for the pattern is agreed with the manufacturer and mainly depends on the specific application. However, the main idea of the textures is to use them where surfaces are susceptible to accidental knocks and scratches. Therefore, damages are less likely to be noticed.

It meets a diverse range of market needs including steel grades, finishes, and other specifications to meet customer requirements.
Stainless steels are one of the more difficult materials to machine. The addition of sulfur to ease machinability, as in austenitic grades such as 303, are still prone to built up edge, difficulties in maintaining a good part surface finish and reduced tool life. Reducing this sulfur addition as needed in 304 and 316, make these matters even worse and adds reduced chipping tendency to the list. Alchemists have searched high and low to find the recipe that turns lead into gold. Steel producers searched for a formula for stainless steels that would make these materials friendlier to machinists.
Back in the early to mid 20th century, metallurgical scientists discovered the usefulness of sulfur in stainless steels. They found that sulfur forms compounds in the stainless steels that will help break the stainless steel chip during machining and form a lubrication layer on the top of the cutting tool, reducing friction and extending tool life. The use of sulfur expanded throughout the stainless industry to give rise to free machining grades such as 303, 416 and 420F.
However, there is a dark side to these high sulfur additions. Sulfur attacks the good attributes of stainless steels. Corrosion is compromised, interferes with welding and can become an initiation site for cracking to occur, especially when any deformation is performed on the part or when there are thin wall sections. The use of sulfur also found its way into other common stainless grades410, 304/304L and 316/316L to name a few. The adverse effects of sulfur in these grades are not as pronounced on properties as the free machining grades. Welding, corrosion resistance, ductility are generally not an issue. These small sulfur additions do have a substantial effect on the machinability of the stainless steels, as a 0.005-percent increase can increase machinability by 50 percent or more.
So how does one further the enhancement of stainless steel machinability? One way is to maximize sulfur levels. Technical literature and industrial studies, however, seem to indicate that sulfur has diminishing returns on machinability with increasing sulfur levels. Figure 1 shows machining data generated by stainless manufacturer, Ugitech, for 303 at varying sulfur levels higher than 0.15 percent. This graph validates published literature to show that more sulfur, especially at levels beyond 0.30 percent, shows a diminishing return for machinability. The main culprit is the loss of lubricity at the elevated machining temperatures or machining speeds. At that point, the sulfur acts mainly as a chipbreaker and stops lubricating the tools. Sulfide size and distribution factors also play into machinability.
Modifying chemistry and/or changing manufacturing process parameters can provide modest gains in machinability, but these are still the limitations sulfur provides at the higher machining speeds. At its research center in France, Ugitech took a different approach and found a way to reformulate the stainless steels without affecting the mechanical and physical properties. This reformulation changes the hard abrasive oxides that normally exist in all stainless steels to create a high temperature lubricant to coexist with sulfur, achieving higher machining speeds.
In every heat of stainless steel, various oxides, such as those in Figure 2, exist as hard and abrasive particles. These oxides, in contact with the cutting tools during machining, cause tool wear and additional heat, leading to premature failure of the tooling. However, if these oxides were changed into ones that are ductile and malleable, these new oxides provide a substance that has high temperature lubrication properties and will act as additional chipbreakers. Ugitech named this controlled oxide Ugima.
These claims become evident when you see these oxides elongate much like sulfur during the hot rolling process (Figure 3). This claim is further validated by X-ray chemical analysis of a tool surface (Figure 4). Both manganese sulfides and the controlled oxide chemical signatures are found on the tool surfaces. This all translates to a 25-percent higher machining speed capability based on 303 stainless machining tests (Figure 5). One additional observation, the machinability of the Ugima 303 does not taper off as the AISI 303, leading to a synergy found between the controlled oxide and sulfur.
One case study to exemplify the machinability of theses grades is a 303 job illustrated in Figure 6. Made from -inch round 303 on a Schtte CNC eight-spindle multi, the part is complex with several slotted grooves on the surface as well as two straight knurls in both outer diameters of the part. The holes are both drilled and reamed, and during the transition to the 303 Ugima bars, the customer added an internal thread. Upon completion of the machining optimization, the customer was able to decrease cycle time by 45 percent to 8.3 sec. (Table 1), giving them a 74-percent increase in parts per hour. As an added benefit, most of the tooling experienced increases in life. This translates into a cost savings of $0.24/part (given a $100/hr. machine cost at 80-percent efficiency) and an 81-percent increase in the parts per hour.
Consistency is another important attribute in machining and is just as important as reducing cycle time. Machinists do not want to set up the machine for a new bundle of stock. The Ugitech mill has developed manufacturing methods to provide the best product for their machining customers, allowing very little variationevery order used in a machine shop should see the same machining behavior heat after heat, order after order.
The best example of this consistency is a shop that used 316/316L Ugima for a small job that came around once a year. The shop optimized their setup on the material and made the parts. One year later, the customer purchased another bundle of 316/316L. Using the same tools, machine, CNC code, and so on, the job was not running well. After some digging, the shop found that it replaced the same coolant from another manufacturer. Once the original coolant was replaced, the job was running as before. This type of consistency is valued by both shop owners and machinists.
Ugitechs controlled oxide, high machinability stainless steels are available in the common stainless grades. This technology, along with consistent manufacturing and combined with technologies such as SMQ (Swiss Machine Qualitya precision cold drawn bar with Swiss tolerances and superior bar straightness), is resulting in drastically reducing machining costs and remaining cost effective in this highly competitive market.

A young Frederick Christian Ulbrich Sr., who worked as a scrap inspector for United States Steel Company in Donora, Pennsylvania, realizes the steel industrys need for good quality scrap. With just a few dollars in his pocket, Fred returns to his hometown of Wallingford, Connecticut, and opens a scrap yard named "The Fred Ulbrich Company".
The first of many expansion moves by Ulbrich occurs in 1927 with an enlargement of the original 600 sq ft building to a 1200 sq ft building. In order to match the rapid growth of the stainless steel industry, Ulbrich decides to increase inventories. Fred Sr. develops an advanced understanding of the metal industry and attends night courses in Metallurgy at Yale University for several years.
The Stock Market Crash of 1929 signals the beginning of the 10-year Great Depression. It represents the most devastating stock market crash in the history of the United States of America. Ulbrich manages to stay in business amidst dire economic conditions.
Fred Ulbrich Sr. devotes his time and energy into growing his scrap yard business. Fred Sr. is able to turn a profit from the occasional sale of scrap to the nearby Ludlum Corporation and through other business ventures such as operating a chicken coop on the premises.
The Ludlum Corporation merges with the Allegheny Corporation. Due to the merger, Ulbrich could no longer sell scrap metal directly to the company. Fred Sr. pivots and pursues a new stainless steel venture.
At this time, the Wallingford-Meriden area was a national hub for cutlery manufacturing. With his knowledge of stainless steel, Fred Sr. establishes a subsidiary company called "Victory Cutlery Company" manufacturing diner-quality cutlery: knives, forks , and spoons. The items are of high quality, yet inexpensive to produce.
Fred Sr. becomes successful and well known in the Wallingford, Connecticut area as one of the town's most successful businessmen and active member of the local community. Germany invaded Poland, signaling the start of World War II.
At the beginning of World War II, Ulbrich wins a federal government contract to supply stainless steel mess kits (forks, knives and spoons) for the United States Army. Because of the war effort, demand for stainless steel skyrockets. With earnings made his cutlery business, Fred Sr. purchases one of the first Sendzimir Rolling Mills and a slitter machine to precisely manufacture stainless steel strip with various thickness and widths.
Ulbrich fulfills orders more rapidly thanks to the Sendzimir Mill purchase. This new rolling mill technology gives the company the capability to convert stainless steel and other metal alloys to more exact specifications. Consequently, Ulbrich receives additional contracts, becoming a major supplier of mess kits during the war.
Fred Sr. becomes the Warden of Wallingford on January 1, 1944. He is re-elected twice, each time winning by more votes than the previous election. As a pro-business Democrat, one of his major accomplishments is paving roads with real asphalt in the Shupeck district on the west side of town.
After World War II, the company expands its cutlery business, offering two distinct products: one being a continuation of the low-cost, diner-grade cutlery, and the other, a high-end line of stainless steel carving knives with elk horn handles, sold in New York department stores. Ulbrich is now four times its original size and its manufacturing facility, now a 2500 sq. ft. building. Fred Sr. and his wife Ada have a growing family of three sons and one daughter. Fred Ulbrich Jr. begins his career at the company as a factory worker.
The company thrives during this time period. Applications for stainless steel multiplies. Fred Sr. has the knowledge, experience and the technology needed to fill an important industry niche. Large "melt mills" such as US Steel sell stainless steel strip on 10,000 pound coils, far too much for small manufacturers to keep in their inventory. Fred Sr. plans to buy these large coils in various gauges (thickness) and to slit them to narrow widths. Customers are able to order quantities of stainless strip as small as 10 pounds with precise specifications. In only three years, sales jump from $102,000 to $425,000.
Re-rolling and slitting strip metal is now the focus of the Ulbrich's enterprise. The cutlery business is sold and a new, more powerful Sendzimer mill is purchased. The unique design of this 20-high cluster mill enables Ulbrich to roll strip to gauges that are unheard of at the time (down to 0.005 inches thick) while retaining the desired flatness of the strip.
Nickel-based alloys are added to the product mix as Ulbrich makes a bid to supply the booming aircraft and aerospace industries. Inventories include 20 alloys of stainless steel, and over 40 types of special metals totaling a constant inventory of over 5 million pounds. Richard (Dick) and Daniel Ulbrich, sons of Fred Sr. enter the business.
The company invests a full year of profit into a testing laboratory in order to qualify as a supplier for Pratt & Whitney Aircraft. After Ulbrich earns approval as a certified supplier, the company earns the business of Boeing, North American Aviation, Rohr, and other subcontractors. Ulbrich is selected as a supplier to the Air Forces B70 Bomber project. This requires the company to roll extremely small gauges, down to .001 of an inch.
Through the publication of monthly newsletters and the development of an in-house sales team led by Fred Ulbrich Jr., major original equipment manufacturers (OEM's) begin to respond to Ulbrich's quality and versatility. Ulbrich earns the moniker as The Biggest Little Mill in the Country and seeks to expand operations. A national distribution network is needed to service the company's nation-wide customer base. Ulbrich of Illinois, located in Alsip, is founded in 1968 as Ulbrich's first stainless steel strip service center.
Neil Armstrong walks on the Moon. NASA's Apollo 11 spacecraft is built using state-of-the-art technology and various metal components rolled by Ulbrich. The company is incorporated and renamed "Ulbrich Stainless Steels & Special Metals, Inc.
Fred Ulbrich Sr. transfers ownership of the company to his three sons, Fred Jr., Dick, and Dan. Ownership reinvests into the business by modernizing the production facilities and increasing capabilities and capacity. Significant new equipment additions are made to improve quality and to roll even smaller gauges. The company earns over $10 million in annual sales, boasts 60 employees working 3 shifts, and offers over 50 different types of metal alloys.
Fred Jr. and brother Dick set a target of $100 million in sales by 1990, and they set in motion plans to reach that goal. They decide to reinvest all corporate profits into new capital expansion programs. Ulbrich breaks into international markets and new economic sectors.
A 100,000 square foot building is erected next to the main plant on Route 5 (South Colony Road) in Wallingford, Connecticut. A regional service center, Ulbrich of New England, is created to more readily service customers. After a series of strategic meetings, company management introduces the "Ulbrich Revolution". Already known for its excellent quality, Ulbrich sets the bar higher by emphasizing the quality, customer commitment and professional development.
Thanks to expansion and a larger footprint throughout the United States, Ulbrich services of several industrial and consumer markets including automotive, aircraft, aerospace, medical, electronic, and power generation. Sales reach $100 million.
Customers seek more specialized products that are more challenging to produce. Ulbrich responds by upgrading its operational capabilities and even greater focus on improving quality. Habitual meetings between machine operators, supervisors, and managers are held on a regular basis. A new company philosophy emerges in the form of these Four Tenets: Total Customer Responsiveness, Total Company Involvement, Total Quality Commitment, and Continuous Professional Development.
Ownership and top management embark on an initiative to increase international sales. Partnerships in France, Japan, and China are brokered. Ulbrich purchases Aerodyne Alloys in Hartford, Connecticut to broaden the companys product line into stainless and nickel alloy bar, sheet, and plate.
The third generation of the Ulbrich family takes the helm with the appointment of Chris Ulbrich as President. A new stainless steel service center is founded in Queretro, Mexico to supply Central and South American markets. Meanwhile, Ulbrich of Illinois celebrates its 30th year in business. Sales reached $250 million a year.
Ulbrich marks its 75th Anniversary with over 600 employees and 18 facilities in four countries. At the time, Ulbrich is buying over 140 alloys from various melting sources in order to maintain their commitment to customers and quick delivery.
Ulbrich acquires Steel Heddle, and transforms the business into a flat wire division - Ulbrich Precision Flat Wire, located in South Carolina. The manufacturing facility expands Ulbrich's capabilities to produce fine wire for the medical industry and Photovoltaic Ribbon to the solar industry.
Ulbrich Stainless Steels & Special Metals Ltd., Shanghai representative office, opened in China. Ulbrich Precision Metals Ltd., located in Ireland, is created and equipped to handle supplying fine wire to the medical industry in Ireland, and the EU.
Ulbrich acquires Delta Precision Alloys whose capabilities in ultra fine wire and plating enhanced the product offerings for the Ulbrich Specialty Wire Group. Ulbrich then opened another company and facility for the precision flat wire product, Ulbrich of Austria.
Ulbrich Specialty Strip Mill adds a 12,000 square foot expansion to house a new ultralight foil, including a rolling mill, annealing line and slitter capable of processing stainless steel and special metal to gauges less than .0004 of an inch.
Ulbrich becomes a global manufacturer of shaped and flat wire, with five facilities located in the major markets throughout the world. Ulbrich suffers first annual loss in 20 years due to Global Financial Crisis, but the company withstands the downturn.
Ulbrich continues into the family's fourth generation with over 700 employees, 12 international locations, and annual sales grow to $300 million. A new Corporate Headquarters is established in North Haven, Connecticut. Manufacturing precision strip and wire remains the main focus.
Ulbrich Precision Special Metals (Suzhou) Co. opens in Jiangsu, China, providing stainless steel and special metals strip. Ulbrich Asia Metals Malaysia opens in Penang, Malaysia, offering a new Precision Coil Center specializing in light gauge stainless steel and special metals strip.
Ulbrich Specialty Wire Products expands into the High Performance Cable market. Ulbrich Shaped Wire runs its first production of the new Fuhr Shaping Mill, expanding its business in the wedge wire market.
As the company celebrates its 90th anniversary, three members of the fourth generation are employed in the family business. During this year, Ulbrich establishes its commercial strategy as being a development partner and supply chain partner.
The Fred Ulbrich Memorial Fund is established to honor and continue the philanthropic work of the late Fred Ulbrich Jr. The fund supports youth development organizations and initiatives in the Wallingford community.
Ulbrich announces the opening of a new sales office in Fresno, California, to better serve the West Coast. The following month, Ulbrich Shaped Wire completes construction of a 17,000 square foot warehouse. In October, Ulbrich of Illinois installs its ninth and most versatile slitting machine yet; the new 24 Stanat Slitter.
In an effort to unify Ulbrichs community outreach programs and events that employees have championed over the years, the Ulbrich Community Outreach Team is formed. Ulbrich fully commits to the Lean Philosophy by completing over 600 A3s in 2016.
Ulbrich closes the year having sold 162 different alloys to customers in 46 countries. The Ulbrich family commits $80 million in capital expenditures to further support the business in its endless effort to exceed customer expectations.
Diversified Ulbrich is more than ready for a new business location as they have been located in the same facility in Downsview for over forty years, with limited space for showcasing their newest product lines. This additional space, including six additional loading docks, will add increased functionality, allowing orders to be filled and delivered faster.
Ulbrich quickly adapts to new ways of working in order to keep employees safer as the COVID-19 pandemic sweeps the world. A new high-tech advanced rolling mill is added at USSM as part of Ulbrichs commitment to continuous improvement initiatives.
