据苏联专利发明证书1198129号报道,苏联研制成功一种用于制造航空航天工业用薄壁零件的马氏体时效钢。 这种钢具有高的强度、硬度和塑性。和以往制造类似的薄壁零件用钢相比,新研制的这种钢的硬度要高28%,强度要增加17%,而塑性增加了20%。 According to the Soviet Union Patent Invention Certificate No. 1198129 reported that the Soviet Union successfully developed a used in the manufacture of thin-walled parts for the aerospace industry martensitic steel. This steel has high strength, hardness and plasticity. The hardness of newly developed steels is 28% higher, 17% stronger and 20% more plastic than previously used for thin-walled parts.
