Forging
Forge by heating slowly and uniformly to 1000°C. After forging cool slowly in furnace or thermoinsulating material.
Annealing
Heat slowly to 780°C. Cool slowly in furnace at a slow rate to 600°C and then cool in air.
Stress Relieving
When heavy machining and/or grinding has been carried out, stress relieving is advisable to minimise the danger of distortion or cracking during the subsequent heat treatment. To stress relieve, heat the tools slowly to 650°C, soak for a minimum of two hours per 25mm of section and allow to cool down in the furnace to 500°C then continue to cool freely in air. The tools can then be finish machined, leaving on an allowance for final grinding after hardening and tempering.
Hardening
Pre heat to 600-700°C until heated through. Continue heating the component to the final hardening temperature of 980-1050°C and allow to be heated through. Protect the component against decarburisation by using a neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tampering
Heat the 1.2083 uniformly and thoroughly to the selected tempering temperature and hold at heat for one hour per 25mm of total thickness. Double tempering is recommended. To achieve the best permutation of hardness, toughness and corrosion resistance it is recommended to temper at 250°C.
