【摘要】 概述了蒸汽轮机用叶片钢的研究进展,对铁素体系叶片钢,HR1200、TOS203有可能作为620℃～650℃的叶片材料;对于高温合金叶片,M252、R-26具有应用前景。以上钢种用作叶片钢但还需要进行进一步的研究、完善工作。更多还原

【Abstract】 Review and prospect of blade steel used for steam turbine has been summarized in this paper.Both HR1200 and TOS203 are possible to use for ferritic blade steels of steam turbine served at 620～650℃.As for Superalloy blade,both M252 and R - 26 Superalloy may have better application.It is necessary to make a further research for above steels used for blade steels in advance.更多还原
