What Is Tempering A Metal Processing - mahamayaresidency.in

Tempering is a process of heat treating, which is used to increase the toughness of ironbased alloys.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 period of time, then allowing it to cool in still air.


Hardening, Quenching, Tempering at Metlab of Wyndmoor PA.

Tempering is the process of reheating the steel at a relatively low temperature leading to precipitation and spheroidization of the carbides present in the microstructure. The tempering temperature and times are generally controlled to produce the final properties required of the steel.
