Martempering Treatment

Martempering process

Martempering is also known as ‘marquenching’, this treatment uses an elevated temperature quench. Components are heated to the austenitizing temperature range and quenched, normally in molten salt at a temperature above the martensitic transformation start point (Ms). Components are held in the quenching medium for sufficient time until the temperature of the component is uniform and then air cooled through the martensite formation range.

This is effectively a harden and temper operation at the same time, keeping distortion to a minimum. Subsequent tempering is carried out to improve the materials toughness.

Benefits of Martempering

Results in properties which combine good wear resistance, high strength, ductility and toughness.

Typical materials that can be treated:-

This process is limited to selected carbon and low alloy  of suitable section sizes.
