DIN 1.7323 Heat Treatments
- Carburizing at 880 - 980°C. Core-hardening at 860 - 900°C, case hardening at 780 - 820°C, quenching. Tempering at 150 - 200°C.
- End quench test: Quench from 910°C Carburizing: 880 to 980°C; NOTE: If steels are direct hardened, in general, a carburizing temperature of 950°C is not exceeded. For special procedures, for example under vacuum, higher temperatures (for example 1020 to 1050°C) are not unusual. Core hardening: 860 to 900°C; Case hardening: 780 to 820°C; Tempering: 150 to 200°C (as a guide, for 1 hour minimum).
