Product Description


321 stainless steel is a material with excellent high temperature stress breaking performance and high temperature creep resistance, and its stress mechanical properties are better than 304 stainless steel. due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature strength, which effectively controls the chromium carbide form.
