Din 55nicrmov7 Material Quenching And Tempering Process - China

Quenching process

The quenching process of DIN 55NiCrMoV7 material is usually oil quenching or water quenching.

The quenching temperature is generally between 860-880℃, and the holding time depends on the thickness and size of the workpiece.

The selection of quenching medium should be determined according to the shape, size and quenching requirements of the workpiece.

Tempering should be carried out in time after quenching to eliminate internal stress and improve the toughness of the steel.

Quenching and tempering process

The quenching and tempering process of DIN 55NiCrMoV7 material is a heat treatment process between quenching and tempering.

Quenching and tempering can further improve the strength and toughness of steel and improve the cutting and welding performance of steel.

The quenching and tempering temperature is generally between 650-700℃, and the holding time depends on the thickness and size of the workpiece.
