Influence of Cryogenic Treatment on the Tribological Behaviour of AISI H21 Tool Steel

Influence of Cryogenic Treatment on the Tribological Behaviour of AISI H21 Tool Steel

The aim of the present work was to find out the optimum cryosoaking duration of deep cryogenic treatment to reduce the wear rate. The AISI H21 hot work tool steel specimens were hardened at 1195 ºC, cryotreated at -185 ºC for 6 to 30 h, double tempered at 540 ºC and soft tempered at 100 ºC. The hard...
