Ok, but there isnt a lot of alloy in it, except for tungsten, its similar to W2 and I havent had issues with forging W2 or 26c3 at the same or similar temps. Would the tungsten cause that much issue? What would be the upper limits for temp, Im using a single burner forge although I did have the psi up high.
I have a few feet, so I'll try again with my thermocouple in and maybe try with some san mai as well.
According to GFS
C: | W: | Mn: | Cr: | Si: | P: | S: |
1.13% | 2.23% | 0.24% | 0.42% | 0.2% | 0.012% | 0.016% |
with their HT
Heat Treatment Cycle:
Normalise at 850 - 880C for 5 to 10 minutes, air cool to room temp
Heat to 810 - 820C and hold for 5 minutes (66HRc as quenched)
Oil Quench (Suggested Oil is Rye 32)
Temper twice for two hours at 200C for 64HRc
I havent read anywhere about it being hot short, although my thoughts are that I may have forged it too long but Ive read and watched the kitchen knife guys who are using it at much thinner blanks and cold forging as well, yet having very few problems. Or at least not reporting them.
I'll try it in a few more ways with better temp control and post up later.
