Abstract

The structure and properties of 20Kh13 (0.2 C–13 Cr) steel are studied after hightemperature thermomechanical treatment (HTTMT) carried out by rolling at 950–900 °C at low strain rate (1 s–1) and up to 30 % true strain. It is found that HTTMT greatly improves impact toughness of the steel after high-temperature tempering. In addition, this treatment effectively retards temper embrittlement by preventing intergranular brittle fracture
