HARDENING:
Hardening should be done in controlled atmosphere, vacuum or fluidised bed furnaces. Preheat slowly to 450/800°C then raise to 1000/1030°C, holding for sufficient time to attain uniformity
throughout the tool, air cool.

TEMPERING:
Tempering should be carried out immediately after air quenching. Heat to 550/650°C, holding for one to three hours. Tools benefit from multitempering and a minimum of two tempers is recommended. Care should be taken to ensure tools cool to room temperature in between tempers. Also suitable for both bath and gas nitriding.
