Heat Treatment
Hardening: Pre-heating temperature: 600–850°C (1110– 1560°F), normally in two pre-heating steps. Austenitizing temperature: 1020–1050°C (1870– 1920°F), normally 1020–1030°C (1870– 1885°F). Quenching media: High speed gas/circulating atmosphere. Vacuum (high speed gas with sufficient positive pressure). An interrupted quench is recommended where distortion control and quench cracking are a concern. Martempering bath or fluidized bed at 450– 550°C (840–1020°F), then cool in air. Martempering bath or fluidized bed at 180–220°C (360–430°F) then cool in air. Warm oil.
Tempering: See the diagram.
