Stainless steel 321 detailed introduction
Stainless steel 321 basic characteristics
Stainless steel 321 belongs to Ni-Cr-Ti austenitic stainless steel, equivalent to domestic 0Cr18Ni10Ti, the US grade is 321, S32100, TP321, and the Japanese grade is SUS321. It contains high chromium (Cr) and nickel (Ni) elements, and has added titanium (Ti) as a stabilizing element. This gives stainless steel 321 excellent mechanical and chemical properties at high temperatures, as well as good corrosion resistance.Stainless steel 321 chemical composition
