摘要
对在炼油厂催化裂化高温烟机入口管线上使用的 1Cr18Ni9Ti不锈钢的组织进行了试验分析 ,同时研究了其组织的变化对不锈钢力学性能和物理性能的影响。结果表明 :不锈钢高温使用性能的变化是管线裂纹失效的主要原因 ,这对今后
The experimental analysis of microstructure was carried out on the stainless steel (1Cr18Ni9Ti) which was used as pipeline of entrance to gas turbine of catalytic cracking at high temperature in oil refinery. The effect of the microstructure on mechanic properties and physical properties was also studied. From this analysis, it can be found that the change of high temperature operating properties of the steel is the major factor of pipe cracking failure.
