ISO X 9 CrNi 18-8 (NS) Heat Treatments


  • Spring hardening: 250-425°C (30 min. to 4 hours), air cool; Tension springs with initial tension are not to be treated at the same high temperatures as the springs. If a moderate loss of initial tension can be accepted, tempering temperatures of max. 200°C.
