The technical process involves heating the metal in such a way as to produce fine particles or impurities that impede the movement of defects in the metal's crystal lattice structure. hardening steel. Precipitation hardenable stainless steels can be austenitic (A-286), martensitic (17-4PH, 15-5PH and others) and semi-austenitic (17-7PH, 15-7PH and others). Heat Treating Stainless Steels for Hardness General heat treating of stainless steels may involve quenching and tempering/aging applied to 400-series martensitic and age hardening SS. These alloys were first introduced in 1946 [1] to fill the need of high-strength, corrosion-resistant alloys that would be capable of operating at elevated temperatures. This corresponds to the maximum stress sustained by a structure in tension.
