How To Heat Treat: CPM S35VN
Heat treating S35VN can be done at different levels of complexity. The below is the "ultimate" version from knifsteelnerd.com:
- hold at 2025 F for 15 mins (1107 C)
- plate quench
- liquid nitrogen/cryo treatment for 30+ mins
- temper between 300 - 400 F for 2 hours x 2 (149 C - 204 C)
- (adjust temp for hardness, aim for 60 HRC as a starting point)
A simpler heat treatment recipe that is proven to work but provide a slightly lower HRC:
- hold at 1950 F for 15 mins (1065 C)
- quench in oil
- temper at 400 F (204 C) for 2 hours x 2 for 57-58 HRC
