Product Description

Product Overview

321 stainless steel strip is a Ni-Cr-Mo austenitic stainless steel material with performance characteristics similar to 304 stainless steel. The addition of titanium content provides superior resistance to grain boundary corrosion and enhanced high-temperature strength while effectively controlling chromium carbide formation.
