摘要
研究了10.9级非调质螺栓用LF10Mn2VTiB钢的成份、性能及强韧化机理。该钢的显微组织由贝氏体、马氏体、奥氏体组成,有利于提高强度和韧性。
The Chemical composition, properties and tough-strengthening monism of non-quenching and tempering high strength bolt steel cold-drawn for class 10.9 have been studied. Themicrostructure of this steel was composed of bainite, martensite and austenite which contribute to strengthening and toughening of steel.
