介绍了核反应堆压力容器用钢的国内外发展状况包括成分及性能要求、冶金工艺、热处理工艺、制造及应用现状。探讨了反应堆压力容器用钢的发展方向:材料技术是核反应堆压力容器制造的关键技术

随核反应堆压力容器向大型化和一体化方向发展

具有更高强韧性和淬透性的SA508Gr4N钢将可能逐步替代目前使用的SA508Gr3钢。

Developed status of steels for nuclear reactor pressure vessel at home and abroad is presented including re- querulent for analysis and properties

metallurgical process

heat treatment

and present situation of manufacture and application. The developed trend of steels for nuclear power station is discussed

as the structure material technique is key technique for manufacturing nuclear reactor pile development of reactor to large-scale and integration

the steel SA508Gr4N which has higher strength-toughness and hardenability shall replace the current steel SA508Gr3 step by step.
