430 Stainless Steel Bar
430 stainless steel is a ferritic stainless steel primarily alloyed with chromium, offering good corrosion resistance in mildly corrosive environments and excellent resistance to stress corrosion cracking. Typical chemical composition includes 16.0–18.0% Cr, ≤ 0.12% C, with no intentional nickel addition, making it a cost-effective alternative to austenitic stainless steels.
Due to its ferritic structure, 430 stainless steel exhibits good formability, moderate strength, and excellent thermal conductivity, along with stable performance under cyclic heating conditions. It also provides good polishability, making it suitable for applications where surface appearance is important.
