660MW锅炉采用的2种新钢材及焊接工艺

Two types of new steel material for 660MW boiler and their welding process

在超临界和超超临界机组中,T92/P92钢和超级304钢的应用越来越多。在参考了国内、外文献资料的基础上,介绍了T92/P92钢和超级304钢的研制过程及2种钢材的性能,分析了2种钢材的化学成分,论述了它们的焊接工艺及焊接方法。

In supercritical units and ultra-supercritical units,the T92/P92 steel and Super 304 steel were more and more used.Referring domestic and abroad documents and materials,the developing process and the performances of T92/P92 steel and super 304 steel were introduced,the chemical compositions of the two steels were analyzed,and their welding process and welding method were discoursed.
