Heat Treatment
Hardening: Preheating: 600–750°C (1110–1380°F). Austenitizing temperature: 950–970°C (1740– 1780°F), normally 960°C (1760°F). Quenching media: Forced air/gas. Vacuum furnace with sufficient overpressure. Martempering bath or fluidized bed at 200–550°C (320–1020°F) followed by forced air cooling. Oil.
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F). Holding time at temperature minimum 2h.
Diagram note: No data.
