What is a Stainless Steel 321 Flanges ?

Stainless Steel 321 Flanges made by Grade 321 shares similarities with 304, it is also austenitic alloy but with the abundance of five times the carbon content and addition of titanium. Due to high concentration of carbon in this steel alloy, there’s no chance of carbide precipitation during welding. SS 321 Slip on Flanges offers excellent immunity to corrosion and oxidation. SS 321 Weld Neck Flange is amazing with its mechanical properties and therefore can be used in high temperature environments. In comparison to SS 304, SS 321 is more suitable to resist creep and stress rupture. The presence of high nickel and chromium makes this alloy excellent for overall corrosion resistance.
