摘　　要：P91由于具有良好的高温性能而受到广泛应用。但由于产品质量参差不齐导致P91钢管在使用过程中可能会出现质量问题。因此对P91钢管的热处理制度进行了简单探讨,同时对硬度、显微组织、化学成分、冲击功、夹杂物及工艺性能等进行研究,指出了材质优劣的鉴别方法。As having excellent high temperature mechanical property, Pg1 is extensively used. But because of having different quality properties, quality problem may be appeared. The research of heat treatment for Pgl pipe has been discussed. Also, hardness, microstructure, chemical, impact, non-metallic inclusion and processing property have been discussed. The method of distinguish different properties are also gived in this paper.

关 键 词：P91钢管 质量鉴别 性能
