Description
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.
