    Abstract: A carbon steel with high hardenability is characterized by being composed of about 0.8% C, 0.1-0.25% Mo, 0.4-0.6% Cr, 0.4-0.6% Si and inevitably added impurites. Si induces synergistic effect with Mo and Cr, so the carbon steel needs less alloying element but doesn't lose its own properties.

    Abstract translation: 具有高淬透性的碳钢的特征在于由约0.8％的C，0.1-0.25％的Mo，0.4-0.6％的Cr，0.4-0.6％的Si和不可避免的添加的杂质组成。 Si引起Mo和Cr的协同效应，因此碳钢需要较少的合金元素，但不会失去其自身特性。
