Type 321 is an austenitic chromium-nickel stainless steel containing Titanium which is recommended for parts fabricated by welding which cannot subsequently be annealed. Type 321 is a stabilized austenitic stainless steel similar to type 304 but with a titanium addition. This titanium addition reduces or prevents carbide precipitation during welding and in 800 - 1500 °F (427 - 816 °C) 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.
