In this paper, it is introduced the micro analysis of microstructure for Q345B high pressure fertilizer pipe with metalloscope aiming at the problem of its unqualified longitudinal impact property and found out its cause is the existence of a large number of Widmanstatten structure. The sample tube was treated with the heat treatment of normalizing process and the results showed that the Widmanstatten structure in steel could be eliminated by normalizing treatment as well as the longitudinal impact energy is greater than 120 J, reaching 3 times of the lower limit value of impact in standard GB 6479-2013.

文章针对Q345B高压化肥管纵向冲击性能不合格的问题,采用金相显微镜对其组织进行微观分析,发现造成冲击性能不合的原因是组织中存在大量的魏氏组织。采用正火热处理工艺对样管进行处理,结果表明:采用正火处理可以将钢中的魏氏组织消除,且纵向冲击功大于120 J,达到GB 6479—2013标准中冲击下限值的3倍。

文章针对Q345B高压化肥管纵向冲击性能不合格的问题,采用金相显微镜对其组织进行微观分析,发现造成冲击性能不合的原因是组织中存在大量的魏氏组织。采用正火热处理工艺对样管进行处理,结果表明:采用正火处理可以将钢中的魏氏组织消除,且纵向冲击功大于120 J,达到GB 6479—2013标准中冲击下限值的3倍。

In this paper, it is introduced the micro analysis of microstructure for Q345B high pressure fertilizer pipe with metalloscope aiming at the problem of its unqualified longitudinal impact property and found out its cause is the existence of a large number of Widmanstatten structure. The sample tube was treated with the heat treatment of normalizing process and the results showed that the Widmanstatten structure in steel could be eliminated by normalizing treatment as well as the longitudinal impact energy is greater than 120 J, reaching 3 times of the lower limit value of impact in standard GB 6479-2013.
