Annealing:
Heat uniformly to 800°C, equalise, then furnace cool. (Hardness about 229 Brinell).
Stress Relieving:
If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalise, then cool slowly.
Hardening:
Heat uniformly to 800/820°C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thickness.
