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.
