To comprehensively understand the domestic and imported 10Cr rotor steels, the chemical compositions and mechanical properties are tested in this study, and the fracture toughness(KIC) is also tested at room temperature and high temperature(600 ℃) using compact tensile specimens. Meanwhile, the relationship among the fracture toughness, impact absorbed energy(KV_2) and ductile-brittle transition temperature(FATT50)of the domestic and imported 10Cr rotor steels are analyzed. The results show that the content...
