ats 34 spring issues
I heat treated my spring at 1900 F for 15 min plate quench and tempered at 1150 for 2 hr twice and after putting the knife together I notice when working the blade that the blade is deforming the spring. I would assume that the spring is to soft. the blade is heat treated as well. Does this make sense and if so can I heat treat the spring again?
thanks |

I usually heat treat ATS between 1925 and 1950, if your oven is running low you could have missed austenitizing temp. If the oven is running high or the thermocouple is off in the lower temperature end, you could have overshot your temper. Looking at the datasheets I'd guess 1100 would be better for a spring temper, since you're already in the high end of tempering I think it would be easy to overshoot if your thermocouple isn't totally accurate in the 1000F temp range.
You can heat treat it again without any problems. __________________ Cap Hayes See my knives @ knives.caphayes.com This quote pains me: -- "Strategically placed blood grooves control blood spray in covert deanimation activities." -- |
