There are many types of surface treatments for stainless steel, including No.1, 2D, 2B, BA, 8K, etc.
No.1 surface: Through hot rolled, annealing, and deoxidation treatment, the surface is rough and matte, it is suitable for industrial applications that do not require high surface smoothness.
2D surface: After cold rolled, heat treatment, acid washing, the surface is matte,it is suitable for processing of deep drawing fasteners.
2B surface: On the basis of 2D surface, bright processing is carried out, which is smoother and flatter than 2D surface, it is suitable for various purposes.
BA surface: The surface is smooth and shiny, it is suitable for high demand surface treatment.
8K surface: After grinding and polishing, the stainless steel surface exhibits excellent gloss and flatness.
These surface treatment techniques not only affect the appearance of stainless steel, but also determine its applicability and service life.
