Forging:
Heat the 1.2550 tool steel component slowly and uniformly to 1000°C. Forge within a range of 1000/800°C, reheating if necessary. Cool slowly (preferably in a furnace) to avoid setting up stresses.
Annealing:
Heat the 1.2550 tool uniformly to 770°C, equalise, then furnace cool.
Stress Relieving:
If machining operations have been heavy or if the 1.2550 tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalise, then cool slowly.
Hardening:
Pre heat the 1.2550 tool steel to 650°C and thoroughly soak. Continue heating to the final hardening temperature of 900/950°C. Allow sufficient time for the component to be heated through. Quench in oil.
Martempering:
Martempering is an alternative hardening procedure for 1.2550 which may be used when suitable salt bath equipment is available.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness.
