Stainless steels are high-alloy steels. They contain about 4-30% of chromium. They are further classified into three types such as martensitic, austenitic, and ferritic steels. Another group of stainless steels are precipitation-hardened steels. They are a combination of austenitic and martensitic steels.
Alloy 350 is a chromium-nickel-molybdenum stainless steel which can be hardnened by martensitic transformation and/or precipitation hardening. It has been used for gas turbine compressor components such as blades, discs, rotors, shafts, and similar parts where high strength was required at room and intermediate temperatures. Depending upon the heat treatment, alloy 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. The corrosion resistance of alloy 350 approaches that of the chromium-nickel austenitic stainless steel

Grade 350 stainless steel alloy can be machined using practices applied on high strength stainless steels. It is recommended to use sharp tooling, positive feeds, slow speeds, and adequate lubricant.
Grade 350 stainless steel alloy can be welded using all common techniques except oxyacetylene welding method. After welding, this alloy is annealed to restore maximum properties.
Hot working of grade 350 stainless steel alloy is performed after heating at 1177°C (2150°F). This process is finished at 982°C (1800°F)
Grade 350 stainless steel alloy can be cold worked in the annealed condition. Radical deformation of this alloy is limited due to its high work hardening rate and the formation of martensite.
Grade 350 stainless steel is annealed by soaking at 1010 to 1066°C (1850 to 1950°F) followed by quenching.
Grade 350 stainless steel is soaked at -73°C (-100°F). It is then tempered at 454°C (850°F) to attain maximum strength or at 538°C (1000°F) to attain maximum toughness and corrosion resistance for 3 to 4 h.
Grade 350 stainless steel can be hardened by sub zero or double aging. Before performing this process, this alloy is prepared by rapidly cooling at 932°C (1710°F).
