321 stainless steel plate is a Ni-Cr-Mo austenitic stainless steel plate. Its performance is very similar to that of 304 stainless steel plate, but due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature resistance.
Chemical Composition
Sulfur: 0.030
Nickel: 9.00-12.00
Chromium: 17.00-19.00
Titanium: 5C-0.70
