441 Stainless Steel Properties Cold Rolled AISI 441 Stainless Steel Sheet

Description:

Type 441 Stainless Steel is a ferritic stainless steel which provides good high-temperature strength (exceeding that of Types 409 and 439 Stainless Steels) plus good corrosion resistance in many exhaust gas environments (equivalent to Type 439 and 18 Cr-Cb Stainless Steels). . Ferritic steels are not inherently strong at elevated temperatures, but columbium additions coupled with appropriate solution annealing markedly improve long-time creep rupture strength. Type 441 is dual stabilized with niobium and titanium to provide good weld ductility and resistance to intergranular corrosion in the weld heat affected zone.
