Quenching And Tempering

quenching

The great benefits of martempering are the lowest grade of size alteration and distortion. The austenitized components are quenched to a temperature close above the martensite starting point to ensure temperature equalization between surface and core.

This allow a martensitic formation being as uniform as possible during further cooling.

Moreover for austempering the AS salts are the first choice as these assure the best attainable toughness.
