Grade 202 Stainless Steel Coils/Strips
What Is Stainless Steel Strips Surface Finish?
Stainless steel has become a widely used metal material for its excellent corrosion resistance, good mechanical properties and processing properties.
Through different processing methods of cold rolling and surface reprocessing after cold rolling, the surface finish of stainless steel can have different types.
The surface processing of stainless steel strips have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.
