Effect of Gas Nitriding Parameters on Microstructure and Mechanical Properties of DIN 1.2367 Hot Work Tool Steel

Abstract

This study investigated the hardness and wear on DIN 1.2367 hot work tool steel after applying gas nitriding processes under different conditions. The impact of the gas nitriding nitrogen potential and retention time was investigated in the group of specimens. The nitriding time and potential nitrogen values in the group had changed, and the diffusion depth and hardness distribution were found to be close. In addition, wear mechanisms were investigated. As the nitriding time and nitrogen potential increase, the wear becomes more brittle. As a result, it was observed that the wear tracks were wider.
