321 stainless steel is Ni - Cr - Ti austenitic stainless steel and its performance is very similar with 304. But due to join the metal titanium, 321 has the better grain boundary corrosion resistance and high temperature strength.
ASTM 321 equivalent material:
GB: 0Cr18Ni10Ti
American: 321、S32100、TP321
Japanese: SUS321
English: 304S12、321920
Germany: X10CrNiTi189
