430 Ferritic Stainless Steel Coil & Sheet – General Purpose 400 Series Grade
Product Overview
430 stainless steel is the most widely used economical grade from the 400 series ferritic stainless steel family. With 16% chromium content and a ferritic crystal structure, it delivers reliable general corrosion resistance, excellent thermal conductivity and good formability at a highly competitive price point. This standard 2B finish grade is optimized for kitchenware, home appliance panels and general fabrication, providing the most cost-effective alternative to austenitic stainless steels for moderate service environments.
