摘要
本文从材料的显微组织、宏观缺陷、化学成分、力学性能等方面，对已服役近１０万小时的９Ｃｒ１Ｍｏ炉管进行了延寿分析研究。结果表明：若仅从蠕变损伤的角度考虑，在正常工况下Ｆ３０１加热炉还有相当长的使用寿命。
his paper researches on life extension of heater tube (9Cr1Mo) after operation for about 100,000 hours at elevated temperature in metallographical analysis,visual defect,test of conventional mechanical properties,test of creep and lasting properties,etcThe results show that a lasting life is expected from the heater under normal operating conditions if only creep damage is considered
