    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 800 – 1500 °F (427 – 816 °C) service. It also improves the elevated temperature properties of the alloy.


    This is the reason for the use of grade 316 (2%Mo) as the standard for marine fittings, and also explains the selection of duplex grade 2205 (S32205)with 3%Mo and adeliberateaddition of0.15%N for resistance to higher chlorides at higher temperatures.
