CarTech 350 alloy is a chromium-nickel-molybdenum stainless steel which can be hardened by martensitic transformation and/or precipitation hardening.

Depending upon the heat treatment, CarTech 350 alloy 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. The corrosion resistance of CarTech 350 approaches that of the chromium-nickel austenitic stainless steels.

Applications:
CarTech 350 alloy has been used for gas turbine compressor components such as blades, discs, rotors and shafts, and similar parts where high strength was required at room and intermediate temperatures.
