Tempered Steel
Tempered Steel
(OP)
I have a piece of alloy-steel round bar(4140) the dimension are 1/2 diameter and 4 long and the steel has been heat treated and tempered to 40-45 Rc I am heating up the end of the steel bar to about 1500 degrees for 10 seconds. My question is when I do this am I effecting the heat treatment or changing the properties of the steel in any way and is there a recommendations for cooling?

10 seconds >>may<< not be enough to reach full tempering effect, and who knows about the cooling rater, but 1500 F is up there
