廉价低镍马氏体时效钢是一种具有发展前景的新型结构材料。这种材料工艺性好,保持足够塑性的前提下具有110～140公斤/毫米~2的屈服强度,而且抗脆性破坏的性能良好在此以前发表的研究成果大都是涉及典型的高镍耐蚀马氏体时效钢的氮化工艺的。对于用其他化学热处理方法去
Cheap low-nickel martensitic aging steel is a promising new structural material. This material has good workmanship and retains sufficient ductility with a yield strength of 110-140 kg / mm2, and good resistance to brittle failure. Previously published research results heretofore involved mostly the typical high nickel corrosion resistant horse Nitrided steel for martensitic steel. For other chemical heat treatment to go
