201 NO.1 stainless steel plate is a hot-rolled austenitic stainless steel available in matte, rough, and industrial-grade finishes. The NO.1 surface is heat-treated and pickled after hot rolling to remove scale and oxides, resulting in a uniform dark gray appearance. This finish is ideal for applications requiring high strength, corrosion resistance, and weldability over decorative requirements.
Compared to 304 stainless steel, 201 grade stainless steel plate has a lower nickel content and a higher manganese content, making it a cost-effective alternative for structural and industrial applications. It offers moderate corrosion resistance and excellent mechanical strength, suitable for environments without strong acid or chloride exposure.
