Forging:
Heat slowly and uniformly to 1100°C. After forging cool slowly.
Annealing:
Heat uniformly to 700°C. Soak well and cool slowly in the furnace.
Hardening:
Heat uniformly to 820/840°C until heated through. Quench in oil, or water.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature, between 550/660°C and hold at heat for one hour per inch of total thickness.
Hard Chromium Plating:
After hard chromium plating, the steel should be tempered for approximately 4 hours at 180°C, in order to avoid hydrogen embrittlement.
Welding:
Firstly heat to approximately 100-350°C. Use an unalloyed basic electrode, for welding unalloyed structural steels.
Normalising:
Normalise at 840-870°C, and cool in air.
Stress Relieving:
After rough machining tools should be stress relieved. Soaking time 2 hours after the whole piece has attained a temperature of approximately 675°C. Cool in furnace to approximately 500°C, and then freely in air.
