  2. Surface Hardening of Stainless Steels

    stainless steel is associated with a loss of corrosion resistance as nitrogen and car-bon react with chromium to form carbides/ nitrides, thus withdrawing chromium from solid solution. In the case of stainless steels, hardening by thermochemical treat-ment has been considered bad practice or a compromise between corrosion proper-

    Jan 02, 2002 · Hardening. Like low alloy steels, martensitic stainless steels are hardened using tempering, quenching and austenitising. Austenitising temperatures range from 980 to 1010°C. At austenitising temperature of 980°C, as-quenched hardness tends to increase first and then drops, following retention.Some results are removed in response to a notice of local law requirement.

    About half of the nickel content of SS304 is replaced with alloy additions of manganese and nitrogen. This results in a higher strength than SS304. Copper is added to compensate for the increased -hardening rate. SS201 thus has relatively lower work ductility and formability compared to 304/301 SS.Some results are removed in response to a notice of local law requirement.
