Forging:Heat slowly and uniformly to 1000°C. After forging cool slowly.
Annealing:
Heat slowly to 780°C. Slowly cool in furnace.
Hardening:
Pre heat to 600-700°C until heated through. (Austenitizing temperature 1025°C.) Continue heating to the final hardening temperature of 980-1050°C and allow the component to be heated through. Protect against decarburisation by using neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per inch of total thickness. Double tempering is recommended.
