In this study, industrial cryogenic process afterconventional heat treatment process for various holding time was applied toAISI D2 (DIN 1.2379) cold work tool steel. The effects of the industrialcryogenic process on the wear behavior was investigated. In the wear test 5,10and 15 N forces were carried out to all group specimens at a constant shearrate (3,16 m/s) and three different wear distances. Experimental results showthat cryogenic processing of AISI D2 cold work tool steels have a significanteffect on wear behavior. It is determined that the cryogenic process increasesthe wear resistance of the samples with increasing sliding time. On the otherhand, the lowest wear resistance was obtained in the as-cast sample. It hasbeen determined that the wear behavior of the AISI D2 cold work tool steel canbe optimized by controlling the cryogenic process parameters.
