Stainless steel mill finishvs 2B

In the No. 3 surface finish, the surface roughness can be up to 1 micrometer. Of course, the surface will have low reflectivity.

Due to high corrosion resistance, the No. 6 stainless steel surface finishing is suitable for marine, architectural and ornamental applications.

However, even as you choose brushed stainless steel surface finishing, it may reduce the corrosion resistance. Remember, the minute lines or groves may make stainless steel susceptible to corrosion.

In all these, the underlying principle was to maintain or improve stainless steel corrosion resistance. Besides, ensuring surface finish guaranteed minimal damage during any use or any application.

By 1970s, scientists from Britain had begun examining effects of polishing stainless steel. This involves series of tests on rough stainless steel surface and smooth stainless steel surfaces.

Even as you choose stainless steel surface finishes, there are two universally accepted standards. These are the EN and ASTM standards for surface finishing.

With a mill finish, you can achieve matte surface finish on stainless steel. In most cases, the matte finish on stainless steel is dull. Therefore, they are not perfect options where aesthetic appearance is a priority.

With grits and an abrasive belt, you can achieve a coarse surface finish, which is uniform. However, the process is suitable for 2.5 mm thick stainless steel. Besides, it is recommended for hot-rolled stainless steel.

It doesn’t matter whether you are using stainless steel tube, stainless steel sheet, stainless steel pipe, stainless steel plate, stainless steel bar, or stainless steel rod.

Additionally, if you intend to process stainless steel further, you can opt for a mill finish. It will still work for you.

TuoLian is a professional stainless steel manufacturer in China. We provide extensive solution including stainless steel sheets, flat bars, rods, angles, and more. Our company serves automotive, fabrication, electrical, architecture, and other industries.

From this stainless steel finish chart, you can see the designation or the number are different. However, in terms of appearance, they are virtually the same.

The final surface is usually smooth. Therefore, you can use 2Q surface finishing in the automotive and medical industries.

Mirror polished stainless steel offer a highly reflective surface with very bright characteristics. Well achieving this kind of surface finishing on stainless steel involves series of processes.

Best finishing on stainless steel improves the overall performance of the material. It is worth noting that the application requirements will determine the specific applications. Let’s compare some common finishes on stainless steel and their application:

With many years of experience, TuoLian Metal becomes the leading manufacturer. We export stainless steel materials to over 100 countries. If you need one-stop stainless steel source, TuoLian has got you covered!

These stainless steel finishes are known for distinct parallel lines on the metal surface. Ideally, they have a muted luster.

A good stainless steel finishing will improve functionality, aesthetic value or appearance. Ultimately, this also affects the stainless steel price.

The No. 4 brushed stainless steel surface finish is suitable for decorative applications in jewelry, automotive design, architectural structures, air conditioners, and home appliances.

Therefore, No. 2D is suitable for surfaces where visual appearance is not a priority. These may include chemical plant equipment, automotive exhaust parts, or roofing accessories.

The result produces stainless steel with a smooth and reflective surface. On average, the roughness is about 0.5 micrometers.

There are many metal surface finishes you can apply on stainless steel metal. Depending on your intended purpose, it is possible to:

Normally, a 2L surface finish is suitable for decorative applications. It is a common designation for all colored surface finishes on stainless steel.

Therefore, No. 2D is suitable for surfaces where visual appearance is not a priority. These may include chemical plant equipment, automotive exhaust parts, or roofing accessories.

These are special surface finishes that are unique to your applications. They vary broadly depending on your specific designs.

Second, the production process is similar to the TR surface finish. Additionally, you require a protective environment for tempering and hardening stainless steel.

Following series of experiments, the matte stainless steel finish No. 2B, brushed stainless steel finish No. 4 and mirror stainless steel finish No. 8 were developed. Since then, many other stainless steel finishing have been developed for various applications.

When it comes to patterned and colored SS surface finish, there is only one ASTM standard. It is the No. 2D surface finish which compares to 2F in EN standard.

You can use 2B matte stainless steel finish in many equipment such as chemical, pharmaceutical, and sewage, among others.

BA stainless steel surface finishing is common in food processing plants, home appliances, road mirrors, surgical mirrors, etc.

As a guiding principle, before choosing any surface finish for stainless steel surface – be clear on what you want to achieve. Whether it is for aesthetic appearance, or to enhance performance characteristics.

Depending on the rolling process, you can achieve about 6 strength levels. The final stainless steel surface finish is reflective and smooth.

Using a 120 to 180 grit belt, you will sand stainless steel material in one direction. Next, you can smoothen the surface using an 80 to 120-grit belt.

You can use stainless steel No. 1 surface finish where visual appearance is not a priority. These may include structural applications, air heaters, furnaces, etc.

Currently, the No.8 mirror finish stainless steel is popular in building column covers, reflectors, mirrors, clean rooms, etc.

Standards play an integral role for uniformity and consistency in stainless steel fabrication industry. Actually, it is from this that stainless steel finishing charts were developed.
