SPECIFICATIONS Type 321 Stainless Steel is covered by the following specifications: AMS 5510 Sheet, Strip and Plate Similar Specifications AMS 5557 Seamless and Welded Hydraulic Tubing AMS 5559 and 5576 Welded Tubing AMS 5570 Seamless Tubing ASTM A 240 UNS : S32100
Type 321 is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 430 - 815°C (800 - 1500°F) service. It also improves the elevated temperature properties of the alloy.
Type 321 provides excellent resistance to oxidation and corrosion and possesses good creep strength. It is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 430 - 815°C (800 - 1500°F).
