1Cr11Ni2W2MoV钢是在12％Cr钢的基础上加入W、Mo、V等合金元素而发展起来的一种马氏体型热稳定不锈钢。由于这种钢具有良好的抗腐蚀性能,又能通过热处理获得高的力学性能,因而被广泛地用来制做航空发动机的压气机叶片、盘及涡轮轴等重要承力零件。该钢在我国航空工业中使用时间较长,暴露出
1Cr11Ni2W2MoV steel is a kind of martensitic thermostable stainless steel developed by adding W, Mo, V and other alloying elements on the basis of 12% Cr steel. Because of its good corrosion resistance and its high mechanical properties by heat treatment, this steel is widely used to make important load-bearing parts for aeroengines such as compressor blades, disks and turbine shafts. The steel used in China’s aviation industry for a long time, exposed
