New Oven/Severe Warpage Emergency
Help!
I've been heat treating 01 blades in my gas forge for several years. Never had much of a problem with warpage. But I just bought an Evenheat Kiln. My first 4 knives have warped severely when I heat treat. So here's what I'm doing. Full speed ramp up to 1475, soak for 20 minutes. Blade warps badly in the oven every time. I can't understand why I never had this problem in my forge. The only difference I see is that the forge brings the blade up to non-magnetic way faster than the oven brings the blade up to 1475. So I did some research and thought I'd discovered the problem. Many knife makers say they run a stress relief cycle before heat treat. They soak the knife at 1200-1300 for 30 minutes and then either air cool or ramp on up to their hardening cycle. So I decided to give it a try. I Slowly heated a blade to 1250 and soaked it for 20 minutes. Guess what? WARPAGE BIG TIME!!!!!! I'm soooo frustrated. What am I doing wrong? Somebody has to know what's going on here. |
