Heat Treat Information

Steels are listed based on Core’s

The following instructions apply to both copper and bronze laminated steels as well.

For Billets with 80crv2 Cores:

  • Normalize at 1600F, 1500F, and 1400F letting cool to black between each cycle.

  • Heat to 1550 F

  • Hold for approx 10 mins for "knife blade thickness"

  • Quench in warm quench oil (not Canola) 86 F-122F 

  • Temper immediately for 2 hours, cool in water and temper for another 2 hours 

For Billets with 52100 Cores:

  • Normalize at 1600F, 1500F, and 1400F letting cool to black between each cycle.

  • Heat to 1550F-1600F

  • Hold for approx 5 mins

  • Quench in warm quench oil (not Canola) 86 F-122F 

  • Temper immediately for 2 hours, cool in water and temper for another 2 hours

For Billets with Damascus Cores:

  • Normalize at 1600F, 1500F, and 1400F letting cool to black between each cycle. 

  • Heat to 1500 F

  • No hold time required, just get the entire piece to this temperature

  • Quench in warm quench oil (not Canola) 86 F-122F 

  • Temper immediately for 2 hours, cool in water and temper for another 2 hours

For Billets with Hitachi Blue #2 Cores:

- Normalize at 1400F, 1300F, and 1250F letting cool to black between each cycle. 

- Heat to 1450F-1525F and quench in warm fast quench oil (Parks 50 or similar)

- Temper immediately for two two hour cycles. (320F-420F depending on desired hardness. 

 

* All heat treating should be performed in a dedicated HT oven that is specifically designed for this process
