Hardening
TemperingHeat uniformly to the selected tempering temperature, hold at heat for one hour per 25mm of thickness. A Double tempering is recommended. It is recommended to temper at 250°C to achieve the best permutation of hardness, toughness and corrosion resistance. Temperature [°C] 100 200 300 400 500 600 Hardness [HRc] 56 54 52 54 53 34
Applications
X40Cr14 is suited for plastic moulds, for acid aggressive plastics, PVC or acetates and with plastics containing abrasive fillers.

Forging
Forge by heating slowly and uniformly up to 1000°C. After forging cool slowly in furnace or using thermoinsulating material.
Annealing
Heat slowly up to 780°C. Cool slowly in furnace at a slow rate to 600°C and then air cool.
Stress Relieving
If heavy machining or grinding work has been carried out, stress relieving is advisable. This will minimise the danger of distortion or cracking during the subsequent heat treatment. To stress relieve, heat the tools slowly up to 650°C, and soak for a minimum of two hours per 25mm of section. Allow to cool 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 heat treatment.
Hardening
Pre heat the component up to 600-700°C and heat thoroughly. Continue heating to the final hardening temperature of 980-1050°C and allow the component to be heated through. Protect the component against decarburisation, quench in oil or air cool.
