新型CrNiMoV钢无塑性转变温度研究

Research on Nil-ductility Transition Temperature of the New CrNiMoV Steel

采用系列冲击试验和落锤试验方法分别测定了新型CrNiMoV钢的无塑性转变温度.结果表明,新型CrNiMoV钢无塑性转变温度较低,具有良好的抗低温脆性破坏性能,满足使用环境对气瓶用钢性能的要求.

The nil-ductility transition temperature of the CrNiMoV steel was determined through series impact test and drop weight test. The results show that the nil-ductility transition temperature of the CrNiMoV is low and the steel has good brittle fracture resistance at low temperature, which can meet the requirement by application environment.
