Cold rolled 2B BA 301 stainless steel in coil sheet strip

Cold-rolled 2B BA 301 stainless steel coil is a metastable austenitic stainless steel material that complies with national, American and Japanese standards, with a thickness range of 0.03-5.0mm and a width of 5.0-1219mm. The 2B surface is a bright surface that has been heat-treated, pickled and flattened after cold rolling, while the BA surface has been brightly annealed and has a higher finish.

301 stainless steel material can significantly improve its strength and hardness through cold deformation processing, with a tensile strength of up to 1500MPa and a Vickers hardness range of 160-600 degrees. Compared with 304 stainless steel, it has a lower chromium and nickel content (Cr 16-18%, Ni 6-8%) and is magnetic after cold processing.

301 stainless steel is widely used in processing scenarios such as electronic appliances, precision parts, and mobile phone accessories. Its wear resistance and fatigue resistance are better than 304 stainless steel, and it is particularly suitable for manufacturing high-strength components such as spring shrapnel.

When purchasing, you need to pay attention to the differences in surface treatment processes: 2B surface is suitable for general industrial use, while BA mirror is used for high-end decoration or precision instruments.
