目前国内生产的汽轮机高、中压整锻转子的材料,基本上采用P_2钢。但是通过多年的生产实践,各方面对这种钢作出了不同的评价,力图研制出新钢种来代替P_2钢。为了给研究新钢种的人们提供一些参考资料,特将苏联对P_2钢的热处理工艺性和机械性能的研究资料摘编于下。 At present, domestic production of steam turbine high and medium pressure forging rotor material, basically P_2 steel. However, many years of production practice, all aspects of this steel made a different evaluation, trying to develop a new type of steel instead of P_2 steel. In order to provide some reference materials for people who study new types of steel, the Soviet Union on P 2 steel heat treatment technology and mechanical properties of the research data extracted in the following.
