441

Type 441 is an 18% chromium, dual stabilized ferritic stainless steel with corrosion resistance similar to that of 304/304L stainless steel. Type 441 has good weldability due to titanium and niobium stabilization and has excellent resistance to stress corrosion cracking.

Properties & Typical Applications

Type 441 is superior to Type 409 in both oxidation and corrosion resistance, with typical applications including automotive manifolds and exhaust system components. The high temperature strength of Type 441 exceeds that of Type 439 and 409 stainless steels.
