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?

Predictable results would require consistent processing. Control the temperature and length of time and cooling rate. Your environment may also need controlling by limiting oxygen and flame settings.
