Cpm 3v


CPM 3V is made by the powder metallurgy process. It is extremely tough and has excellent edge holding ability. The following is the reccomended heat treat for the best combination of toughness and edge holding taken directly from the Crucible website.
1. Heat to 1500-1550 and equalize.
2. Heat to 1950 and soak for 30-45 minutes.
3. Quench in air, positive pressure (2 bar min.), salt, or interrupted oil to below 125 degrees.
4. Triple temper for 2 hours each cycle @ 1000 degrees F.

Times and temps. can be changed in order to increase either edge holding or toughness. People who have actually used a different heat treat process feel free to share any thoughts on the results you've discovered.
