Abstract

Structure formation in electric steel 42Cr4Mo2 under continuous cooling is investigated. The results are given in the form of continuous cooling transformation diagram. It is recommended to cool electric steel 42Cr4Mo2 bar section at the mass-averaged rate 1.0-2.3 °C/s during thermalmechanical treatment for bainite formation, which will allow reducing time of subsequent softening heat treatment.
