一种新型CrNiMoV高强钢低温韧性研究
|
摘要
CrNiMoV钢是一种新型、高强度的特种压力容器材料。通过试验测试其强度、延塑性、冲击韧性、断裂韧度等随温度的变化情况,表明该材料韧脆转变温度较低,具有良好的抗低温脆性破坏性能,能够满足使用环境对其最低使用温度的要求。
The CrNiMoV steel is a new high-strength material for special pressure vessel. By testing the variation of its strength,ductility,impact toughness and fracture toughness with temperature,it was shown that the CrNiMoV steel has lower ductile-brittle transition temperature and better resistance to low temperature brittle fracture,which can meet the requirement of application environment for its minimum allowable service temperature.
