COMPONENT FOR CONSTRUCTION MACHINE
To provide a component for a construction machine which highly has both abrasion resistance and toughness.SOLUTION: A component for a construction machine composed of cast steel containing Fe has such a structure as to contain, by mass%, 0.1 to 0.35% of C, 0.2 to 0.4% of Si, 0.8 to 1.4% of Mn, 0.7 to 1.8% of Cr, 0.2 to 0.5% of Mo, and 0.0 to 0.1% of V, and to mainly contain martensite. The component for a construction machine may contain 0.5% or less of Ni, Nb, Ti and Zr in total.SELECTED DRAWING: Figure 6
【課題】耐摩耗性と靱性とを高次に兼ね備える建設機械用部品を提供する。【解決手段】Ｆｅを含む鋳鋼からなる建設機械用部品であって、質量％で、Ｃ：０．１～０．３５％、Ｓｉ：０．２～０．４％、Ｍｎ：０．８～１．４％、Ｃｒ：０．７～１．８％、Ｍｏ：０．２～０．５％、及びＶ：０．０～０．１％を含有し、かつマルテンサイトを主体とする組織を有する建設機械用部品を提供する。建設機械用部品は、Ｎｉ、Ｎｂ、Ｔｉ、Ｚｒを合計で０．５％以下含有していても良い。【選択図】図６
