Here is a group I just finished up. As I quenched blade after blade, the quench oil was rising above 150 so I wondered how it was affecting the hardening of the steel. I then triple tempered. We have a hardness tester at work so I wanted to find out how good and consistent my heat treat was. The hardness is written on each blade. Blade #1 (starting at the top) is 3/16” 1095. Blade #2 is 5/32” O-1. The rest are 3/32” O-1. The bottom blade has not been tempered and is the last blade I quenched. At this time the oil was 175 – 190 degrees. The numbers (for the O-1) all came back with in 1.5 on the Rockwell C scale.
My question is, how do these numbers look to you guys that have been doing this for a while? Any and all feedback is welcomed!
thanks, Uncle Billy
