Introduction
Stainless steel grade 441 is a ferritic stainless steel containing niobium that provides the steel good oxidation and corrosion resistance. This steel provides good high-temperature strength in exhaust gas environments, and has good for deep drawing, good ductility, good weldability, and good brightness. It polishes well. The 441 flat rolled stainless steel possesses magnetic quality in all conditions.
The following datasheet provides an overview of stainless steel grade 441.
