Type 441 is an 18% chromium, dual stabilized ferritic stainless steel with corrosion resistance similar to that of 304/304L stainless steel. This grade may be used in the annealed, cold formed or as-welded condition in applications where other stainless steels such as Type 304/304L and Type 430 are used. Type 441 has good weldability due to titanium and niobium stabilization and has excellent resistance to stress corrosion cracking. Type 441 outperforms Type 409 in both oxidation and corrosion resistance and typical applications include automotive manifolds and exhaust system components. The high temperature strength of Type 441 exceeds that of both Types 439 and 409 stainless steels.
ASTM A276 Stainless Steel 441 Strips are broadly used in various industries including chemical processing, shipbuilding, pharmaceuticals, petrochemical, building materials, automobile exhaust system, and food processing, etc. Stainless Steel Strips are manufactured according to china as well as International standards like ASME, ASTM, AISI, ANSI, BS, IS, DIN, JIS & more. These SS 441 Strips provide high-temperature strength in exhaust gas environments.
