If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat the tool steel component to 750-800¡ãC. and allow to soak at this temperature. The tools may then be brought up to 1000-1040¡ãC for air cooling, or 980¡ãC for oil quenching. Soak thoroughly at the temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly. It is important not to exceed 1020¡ãC when heating for hardening. 4. 1.2080 D3 Annealing Supplied in the annealed and machineable condition re-annealing will only be necessary if the steel has been forged or hardened by the toolmaker. To anneal, heat slowly and uniformly to 900¡ãC. Soak for three to four hours and allow to cool in the furnace to room temperature. Re-heat to 800-1040¡ãC and again soak for three to four hours. Allow to cool in the furnace to room temperature. 5.AISI D3 Stress Relieving When tools made from 1.2080 tool steel are heavily machined, ground or otherwise subjected to cold work, the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving should be done after rough machining. To stress relieve, heat the component to 600-650¡ãC. Soak well and cool in the furnace or in air. The tools may then be finish machined before hardening.
