AM 350 is a chromium-nickel-molybdenum stainless steel which can be hardened by martensitic transformation and/or precipitation hardening. It offers superior corrosion resistance to other quench-hardenable martensitic stainless steels with good high temperature strength.
Depending upon the heat treatment, AM 350 may have an austenitic structure for best formability, or a martensitic structure with strengths comparable to those of martensitic steels. The alloy normally contains about 5 to 10% delta ferrite and its corrosion resistance of approaches that of the chromium-nickel austenitic stainless steels.
