The cryogenic treatment of die steel 1.2379:
In order to obtain the highest hardness and dimensional stability, the mold immediately after quenching and cryogenic -70 to -80 DEG C, keep 3-4 hours, and then in the tempering treatment, the hardness of the tool or mould of cryogenic treatment than conventional heat treatment hardness 1-3HRC. Parts with complex shape and size changes in the larger, cryogenic treatment has the production of cracking risk.
The nitriding treatment of 1.2379 steel:
The mold or the workpiece after nitriding treatment, surface layer with high hardness and corrosion resistance of the hardened layer.
