摘　　要：在超临界火电机组领域,当前实际应用的铁素体耐热钢最高运行蒸汽温度为620°C左右,德国瓦卢瑞克曼内斯曼钢厂的VM12设计工作蒸汽温度可达650°C,初期的实验室及工业化试制试验结果证明,VM12的抗蠕变及抗蒸汽氧化性能可以满足650°C下服役要求,并具有良好的可加工性。详细介绍了VM12的试验过程及结果。In the supercritical fossil fired power generation field, the highest service steam temperature for heat resistant ferritic steel, actually used at present, is around 620℃ ; but the allowable design steam temperature for VM12, developed by Vallourec ＆ Mannesmann is as high as 650 ℃. Initial laboratorial and industrial tests show, that the creep and oxidation resistance property in steam of VM12 can meet 650 ℃ service requirements, while simultaneously retaining good workability. Tests performed and results obtained are being described in detail.
