Forging:
Heat the 1.2436 tool slowly and uniformly to 700°C then more rapidly to 900/1050°C. After forging cool slowly, preferably in a furnace.
Annealing:
Anneal 1.2436 at 800°/840°C and slow furnace cool. Hardness after annealing will be approx. 225 brinell.
Stress Relieving:
If machining operations have been heavy or if the tool has an unbalanced section, remove stresses from 1.2436 alloy tool steel before hardening by heating up to 650°/700°C, equalise, then cool slowly.
Hardening:
Pre heat the 1.2436 component slowly to 750/800°C and thoroughly soak. Continue heating to the final hardening temperature of 950°/980°C and allow the component to be heated through. Cool in air or quench in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness. Double tempering of 1.2436 is recommended and should be carried out with intermediate cooling to room temperature.
