Investigation of Kinetic Plasticity of High Chromium Steel during Tempering

Abstract

This article presents the results of the investigation of the kinetic plasticity of hardened high chromium steel during tempering at 210 °C – 520 °C temperatures. The researched steel contains 0.19 % – 2.13 % carbon and 12 % – 18 % chromium. The hardening temperatures are chosen from 950 °C till 1100 °C. After the investigation was carried out, the dependence between the content of carbon, temperature of hardening and tempering, normal bending stresses was found. An influence of chromium on steel tempering character was determined. The results of the work may be used for the development of technology of hardening and smoothing of articles and tools.
