Tempering metallurgy
Know More
Tempering is a process of heat treating which is used to increase the toughness of iron-based alloysTempering is usually performed after hardening to reduce some of the excess hardness and is done by heating the metal to some temperature below the critical point for a certain period of time then allowing it to cool in still air The exact temperature determines the amount of hardness...
