420 Martensitic Stainless Steel Sheet Hot rolled / cold rolled 0.4mm - 100mm Thickness

420 stainless steel plate is a martensitic stainless steel with higher carbon content than grade 410, designed for applications requiring excellent hardness, wear resistance, and moderate corrosion resistance. It can be heat-treated to achieve a hardness of up to 50 HRC, making it the hardest among the 12% chromium grades. Grade 420 stainless steel is widely used in cutlery, surgical instruments, pump shafts, valve components, bearings, and plastic molding tools. Its
