摘要
研制的 10t水轮机导叶轴头控氮低碳马氏体高强高韧不锈钢X3CrNiMo13 4大锻件电渣锭利用率达 85 % ;钢锭化学成分均匀 ,低温韧性优良 ,超声波探伤未发现≥Φ2mm缺陷。
The 10t low carbon containing nitrogen X3CrNiMo13\|4 martensitic stainless steel forging for shaft of wicket gate has been produced by ESR process. The yield of ESR ingot was up to 85%, of which the composition was homogeneous and the toughness at low temperature was excellent.The ≥Φ2 mm defect wasn't found in steel by ultrasonic inspection. <
