The Effects of The Industrial Cryogenic Process on The Wear Behaviours of AISI D2 Cold Work Tool Steels

In this study, industrial cryogenic process after conventional heat treatment process for various holding time was applied to AISI D2 (DIN 1.2379) cold work tool steel. The effects of the industrial cryogenic process on the wear behavior was investigated. In the wear test 5,10 and 15 N forces were carried out to all group specimens at a constant shear rate (3,16 m/s) and three different wear distances. Experimental results show that cryogenic processing of AISI D2 cold work tool steels have a significant effect on wear behavior. It is determined that the cryogenic process increases the wear resistance of the samples with increasing sliding time. On the other hand, the lowest wear resistance was obtained in the as-cast sample. It has been determined that the wear behavior of the AISI D2 cold work tool steel can be optimized by controlling the cryogenic process parameters.
