Forging

Forge at 1000°/1050°C.  Heat slowly, allowing sufficient time at the forging temperature for the steel to be thoroughly soaked through. Re-heat as often as necessary to keep the temperature above 850°C. After forging cool very slowly, preferably in a furnace

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.
