Ac3 temp calc
Ac3 temp calc
(OP)
looking for information on the best available formula for calculating Ac1/Ac3 temperatures. I recently made a calculation for a steel grade using two different formulas and the Ac3 temperature varied by +50 deg F.

So, it is not unusual to see a variation in AC3 transformation temperature between several equations because you need to select the correct equation for the grade of steel.
