Heat Treatment
Hardening: Pre-heating temperature: 600–700°C (1110– 1290°F). Austenitizing temperature: 950–970°C (1740– 1780°F), normally 960°C (1760°F). Holding time: 30–45 minutes. Quenching media: High speed gas/circulating atmosphere.Salt bath 200–550°C (390–1020°F). Fluidized bed 200–550°C (390–1020°F).
Note 1: Quenching should not be interrupted until the part has cooled down to 25°C (75°F). Otherwise the part may shrink after tempering.
Note 2: Temper immediately after quenching.
Note 3: Quenching in oil is not recommended.
Tempering: The tempering temperature for the required hardness may be determined by means of the tempering graph. Temper twice. Lowest tempering temperature 200°C (390°F). Holding time at temperature minimum 2 hours.
