What would be considered the the full rockwell C hardness before tempering?
The only numbers I can find are after temper.
At 1900* for 30 min. I got 52-54RC. so I went to 1925* for 15 min. and got RC61-62 plate quenched both times.
I have a small 120V oven that struggles at these temps. so looking for minimum temp. and time but max hardness before temper is priority.
The optimal as tempered numbers are a mater of opinion, but I don't think the max hardness before temper is, correct me if that's wrong.
Thanks for help on this.
