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.
200 SERIES STAINLESS STEEL
200 Series stainless steels are not new – In fact they have been around for many years. To date they have traditionally not proved very popular outside the USA. However, since they have a much lower Nickel content than 300 Series Austentics, the very high Nickel price over recent years has led to significantly more interest. Equally, stainless steel producers have an ongoing programme of development designed to enhance existing grades and produce new grades. These new grades are sometimes developed for specific end uses and sometimes to improve upon an existing grade.
