This paper describes the heat treatment technique to improve the long-term property of high Cr steel in terms of MX precipitation hardening mech anism. The microstructure examinations using optical and electron microscopes and Vicker's hardness tests are conducted. As a result, it is clari fied that fine MX particles are obtained by solution treatment at hot rolling temperature and that the number of particles increases with the no rmalizing temperature. It suggests that MX particles stable at elevated tem...
