Question

Heating the steel to appropriate temperature for a short time and then cooling it rapidly in order to give it the desired mechanical properties is called the tempering. If true enter 1 else 0.

Answer 1

Tempering is a process of heat treating which is used to increase the toughness of iron based alloys such as steel.

Tempering 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 point for a certain period of time, then allowing it to cool in still air.

So, the given statement is correct.
