Protect surface from decarburisation at all steps of the process!!
tecnica
When tempering at 400-750?F (200-400?C), freezing treatments may be necessary to minimize retained austenite.
tecnica
Austenitize: 1900-2000?F (1035-1095?C), hold time at temperature 15-30 minutes.
tecnica
Temper: Double temper at 400-750?F (200-400?C). Hold for 2 hours minimum each time.

NOTE: For optimum stress relieving, CPM S30V may be tempered at 1000-1025?F (540-550?C). Tempering in this range may result in a slight decrease in
