321 stainless steel

321 stainless steel

321 stainless steel / SS321is 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 SS321 equivalent material: GB: 0Cr18Ni10Ti American: 321、S32100、TP321 Japanese: SUS321 English: 304S12、321920 Germany: X10CrNiTi189

The performance of 321 stainless steel plate and 304 stainless steel plate is very similar, all add to the titanium raw material, better resistance to grain boundary corrosion and high temperature strength. The addition of titanium makes an effective control of the chromium carbide formation.321 stainless steel high temperature stress rupture properties and stress mechanical properties are superior to 304 stainless steel.Ti in 321 stainless steel exists as stable, but it is also hot strong steel. much better than the 316L stainless steel at high temperatures.
