摘要
阐述了选用加氢反应器基体材料遵循Nelson曲线的条件及用化学成分控制21/4Cr-1Mo钢回火脆性的问题,并分析了含Si量高的21/4Cr-1Mo钢使用的可能性。
Recounted the condition of Nelson curve that shall be met for selection of base metal of hydrofining reactor,and the probfern to control temper brittleness of -1Mc steel by chemical composition. And analysised the problem about the probability for use of -1Mc with high St content.
