2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – What’s the Difference?

Stainless steel is a widely used metal material. Due to its excellent corrosion resistance and beautiful surface quality, it is widely used in construction, furniture, kitchenware, medical equipment, and other fields. There are many different methods of stainless steel surface treatment, including 2B, 2D, 4B, BA, and NO. 4 surface treatment methods. So, 2B vs 2D vs 4B vs BA vs NO.4 surface finishes – what’s the difference? Below we will introduce them in detail.

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – What’s the Difference?

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – I. 2B Surface Treatment

2B surface treatment is a common surface treatment method, with high surface quality, silver-white color, and good luster and mirror finish. It has good rust resistance and corrosion resistance, and also possesses certain fingerprint resistance. It is commonly used in occasions that require high luster and smoothness.

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – II. 2D Surface Treatment

2D surface treatment is a more rugged surface treatment method, with a non-lustered gray or black appearance. The advantage of 2D surface treatment is its strong fingerprint resistance and rust resistance, and it is relatively low-cost. It is commonly used in structural parts and supports that require high strength and durability.

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – III. 4B Surface Treatment

4B surface treatment is a more advanced surface treatment method, with extremely high surface quality, extremely high luster, and mirror finish. It is suitable for occasions that require excellent surface quality and luster, such as high-end tableware and luxury buildings.

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – IV. BA Surface Treatment

BA surface treatment is a special surface treatment method, also known as “super polishing”, with a silver white or gray appearance, and extremely high luster and mirror finish. It is suitable for occasions that require excellent surface quality and luster, such as high-end decoration and luxury buildings. At the same time, BA surface treatment also has strong fingerprint resistance and corrosion resistance.

2B vs 2D vs 4B vs BA vs No.4 Surface Finishes – V. NO.4 Surface Treatment

NO.4 surface treatment is a more common surface treatment method, also known as “sand” or “satin”, with a non-lustered gray or black appearance. The advantage of NO.4 surface treatment is its strong fingerprint resistance and rust resistance, and it is relatively low-cost. It is commonly used in occasions that require certain rust resistance and luster, such as ordinary buildings and furniture. Additionally, NO.4 surface treatment also has a certain decorative effect, able to bring warm and comfortable visual feelings to people.

Conclusion

In summary, the 2B, 2D, 4B, BA, and NO.4 surface treatment methods of stainless steel have different characteristics and applications. When selecting the surface treatment method of stainless steel, it needs to be based on the specific application and requirements to achieve the best use effect and appearance effect. At the same time, attention should also be paid to the impact of different surface treatment methods on the performance and service life of stainless steel.
