UNI 16 NiCrMo 12 Heat Treatments
- Hot worked at 1100-900°C; Cementation at 870-900°C; Core hardened at 820-850°C; Surface hardened at 780-810°C. Quenched in hot water bath; Stress relieved at 150-200°C.
- Material is normally supplied in the hot rolled condition but subject to agreement may be supplied in one of the following conditions: Soft Annealed (SA). Spheroidise Annealed (Spheroidised). Annealed to obtained a lamellar ferrite and pearlite structure (Annealed). The H + T values shown in the mechanical properties table are obtained from an 11mm test bar hardened by oil quenching from 850°C +/- 10°C after holding at temperature for at least 30 minutes, and tempered at 180°C +/- 10°C for at least 1 hour. Final Heat Treatment: Case harden at 870 - 900°C. Harden the core by oil quenching from 820 - 850°C. Harden the case by oil quenching from 780 - 810°C. Finally, temper at 150 - 200°C.
