Contact.carbon steel strip quench and temperingAug 23, 2014 · I have seen parts made of high carbon steel quenched in water and not tempered explode just setting on a bench. What is said about going from the quench to the temper furnace quickly is true. Why is this not so in tempering? Quenching is a time-temperature relation.
