Heat Treatment:
Soft Annealing: Heat to 680-720ºC, cool slowly. This will produce a maximum Brinell hardness of 248.
Nitriding:
Gas/plasma nitriding temperature (gas, salt bath): 570-580ºC
Gas/plasma nitriding temperature (powder, plasma): 580ºC
Surface hardness after nitriding: 800 HV
Hardening: Harden from a temperature of 850-880ºC followed by oil quenching.
Tempering:Tempering temperature: 570-680ºC.
Application:
Structural parts of medium and large cross sections and high surface hardness, e.g., valve and gate valves, cylinders for combustion engines, superheated steam valves and fittings.
