Heat Treatment & Processing

Typical Heat Treatment Process:

Annealing (for machinability):

Heat to 820–900°C, slow cool (~25°C/hour).

Reduces hardness (~HB 200) for easier machining.

Quenching (for maximum hardness):

Heat to 815–870°C, then rapidly cool in water or oil.

Results in martensitic structure (HRC 60+).

Tempering (to reduce brittleness):

Heat to 150–400°C (lower temp = higher hardness).

Balances hardness (HRC 55–60) & toughness.
