摘要
通过金相分析，常温、高温短时拉伸性能及持久性能试验，对ＨＫ４０ＶＨ再生炉管焊接接头性能进行了评定。结果表明：其性能与国外ＨＫ４０炉管焊接接头性能相当。
By metallographic analysis,short time tensile performance test and endurance life test at ambient and high temperature,the welded joints of HK 40VH reprocessing reformer tube were evaluated The results indicate that their performances are compatible with those of abroad
