摘要
对在加氢反应器内运行近５ａ的２．２５Ｃｒ－１Ｍｏ钢试块进行了２次步冷试验，评定了２．２５Ｃｒ－１Ｍｏ钢的回火脆性。结果表明，对已经回火脆化的２．２５Ｃｒ－１Ｍｏ钢试块不适宜用步冷试验来预测其进一步的回火脆化程度。
The step cooling tests are performed two times for a 2.25Cr 1Mo steel block which had been put into an in service hydrogenation reactor for 5 years,and the temper embrittlement of 2.25Cr 1Mo steel is assessed. The test results show that the step cooling test for the temper embrittled block of 2.25Cr 1Mo steel can not predict the future susceptibility to temper embrittlement.
