摘要
针对超超临界火电机组关键不锈钢材料的使用环境特点,阐述了太钢耐热钢TP310HCbN的设计原理、强化机制、生产工艺流程及主要工艺技术措施。采用TEM、EDS等分析测试方法,对组织、焊缝、析出物进行了细致研究,同时对常规力学性能、高温拉伸性能、持久性能等进行了测试。开发的TP310HCbN耐热无缝钢管组织均匀、综合性能良好,产品已进入批量生产阶段。
According to the characteristics of the environment for the use of ultra-supercritical thermal power units key stainless steel,the principle of the TISCO heat-resistant steel TP310HCbN design,strengthening mechanisms,technical measures and the production process was set forth.The microstructure,weld and precipitates were researched by using TEM and EDS analysis test,and the conventional mechanical properties,high-temperature tensile properties and creep and rupture mechanical were investigated.The development of TP310HCbN heat-resistant seamless steel pipe has uniform organization and comprehensive performance,and the products has entered the stage of mass production.
