Forging
Preheat slowly to 700°C then increase temperature more rapidly to 1050°C. Do not forge below 800°C. It is essential to cool slowly after forging, either in a furnace or in vermiculite.
Annealing
Soak thoroughly at 740-760°C before furnace cooling at a maximum rate of 10°C per hour down to 600°C followed by cooling in air.
Stress Relieving
When tools made from 1.2714 steel are heavily machined or ground, the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving of this grade should be done after rough machining. To stress relieve, heat the component carefully to 600-650°C, allow a good soaking period, about two hours per 25mm of section. Cool in the furnace to 500°C then freely in air. Tools may then be finish machined before hardening.
Hardening
Preheat to 600-700°C. Soak thoroughly, then increase rapidly to the hardening temperature of 850-880°C. Air or oil quench. Tools should be tempered as soon as they become hand-warm.
Tampering
Heat uniformly to the required temperature allowing a soaking time of two hours per 25mm of ruling section. Withdraw from the furnace and allow to cool in air. A second tempering is highly recommended, the tool being allowed to cool to room temperature between tempers.
