Heat treating 80CrV2
80CrV2 is a popular blade steel in Finland, most all of the Lauri, Polar and Laurin and many of the Brisa carbon blades are made in just this steel. It is a steel similar to 1084 with the added Vanadium helping with refined grain size but unlike 1084 this is not a "real" oil-hardenable steel. In small sections like for knife blades a fast oil quench is enough but for larger cross-sections this is a water-quenching steel. We think of 80CrV2 as "1084's angry cousin" where the longer soak time justifies a tough blade.
Heat treating 80CrV2:
- heat to 830 C (1525 F)
- hold for 10 mins for "knife blade thickness"
- Quench in a fast quench oil (not Canola)
- Temper immediately at 204 C (400 F) for 2 hours, cool in water and temper for another 2 hours
- approx 60 HRC
