Key words: Steel for Turbine Blade, X10CrNiMoV12-2-2, Forged Product

摘要： X10CrNiMoV12-2-2钢(%:0.08～0.13C、11.4～12.5Cr、2.2～2.8Ni、1.6～1.8Mo、0.25～0.40V、0.020～0.040N)经20 t EAF-AOD-LF冶炼后铸成Φ490 mm电极,电渣重熔成Φ600 mm钢锭,锻造成Φ180～240mm棒材。检验结果表明,钢中有害元素Sb为0.002%,As 0.010%,Sn 0.010%,其夹杂物级别、晶粒度、力学性能、FATT(脆性转变温度)、晶间断裂百分比、δ-自由铁素体含量均达到技术标准要求。
