| 摘 要： | 1Cr12Mo钢属于马氏体不锈钢，被广泛用于汽轮机亚临界机组的低压叶片。该钢在生产过程中由于冶炼方法的不同其化学成分会在一定范围内变化。对大量生产和试验数据进行分析的结果表明，成分的波动和热处理工艺参数的变化对钢的冲击韧度都有重要的影响。

| Abstract: | 1Cr12Mo steel belongs to martensitic stainless steel and is extensively used for low pressure vanes of the subcritical turbonerator. Its chemical composition will vary with the steel-making technology to a certain extent. Analysis on a large number of production and test data revealed that the fluctuation of composition and the alteration of the heat treatment process parameter will considerably influence the impact toughness of the steel. |
