Effect of deep cryogenic treatment on tribological properties of PM S390 MC high speed steel

Applying the deep cryogenic treatment after quenching it is possible to achieve better wear resistance and fracture toughness on high speed steel. The effect of deep cryogenic treatment on the abrasive and erosive wear of PM S390 MC high speed steel has been investigated in this paper. The obtained results confirm that the application of deep cryogenic treatment results in significantly improved erosive wear resistance, while the abrasive wear resistance depends on the applied temperature of austenization.
