Abstract

　本発明は、Ｓ含有量を低減して強度等の機械的特性を維持すると共に、ハイス工具での断続切削および超硬工具での連続切削の両方で優れた被削性を発揮することのできる機械構造用鋼を提供することを課題とする。本発明の機械構造用鋼は、鋼中に存在する酸化物系介在物が、該酸化物系介在物の平均組成合計を１００％（「質量％」の意味、以下同じ）としたときに、ＣａＯ：１５～６０％、ＳｉＯ２：２０％以下（０％を含まない）、Ａｌ２Ｏ３：２０～８０％、ＭｇＯ：４０％以下（０％を含まない）、をそれぞれ含有すると共に、Ｌｉ２Ｏ,Ｎａ２Ｏ,Ｋ２Ｏ,ＢａＯ,ＳｒＯおよびＴｉ酸化物よりなる群から選ばれる１種以上の合計含有量が０．５～２０％である。
