【Abstract】 This paper studied the fatigue properties （low-cycle fatigue, highcycle fatigue, thermal fatigue） and static and dynamic fracture toughness (K _1d￣J,K_1c￣J) of OCr18Ni12Mo2Ti forging steel. The results show that the fatigue properties and static and dynamic fracture toughness of 0Cr18Ni12Mo2Ti forging steel can meet the safety requirements in ASME code. This material has good comprehensive mechanical properties.更多还原
