1.	For how long is the heated steel held in full annealing process?(a) 1 minute(b) 3 minutes(c) 6 minutes(d) 9 minutesThis question was addressed to me by my college director while I was bunking the class.The origin of the question is Annealing and Normalizing topic in chapter Heat treatment of Metals and Alloys of Casting-Forming-Welding II
Answer» RIGHT answer is (b) 3 minutes To explain: The heated STEEL is held at the critical temperature for about 3 to 4 minutes. By doing this, the steel gets ENOUGH time to make the internal CHANGES DESIRED.
