Forging:

Heat slowly and uniformly to 700°C then more rapidly to 900/1040°C.

After forging 1.2379 cool slowly.

Annealing:

Anneal at 850°C and slow furnace cool.

Hardness after annealing will be approx.

225 brinell.

Hardening:

Pre heat the 1.2379/D2 component slowly to 750/780°C and thoroughly soak.

Continue heating to the final hardening temperature of 1000/1030°C and allow the component to be heated through.

Quench in oil or cool in air.
