通过热力学计算，研究了质量分数为15%Cr、2质量%Mo、不同C、V、Nb和Ti含量的不锈钢，其耐磨性与标准冷作工具钢X153CrMoV12相当。结果表明，Nb最适合形成耐磨MC碳化物，从而减少了M7C3的含量，从而使固溶于基体中的铬含量提高到钝化水平。X140CrNbMoTi15-5-2钢附近的小熔体在淬透性、耐磨性和耐腐蚀性方面证实了这一概念。将讨论新牌号RN15X®的工业制造和应用。
Steels with 15 mass% Cr, 2 mass% Mo and varying contents of C, V, Nb and Ti were investigated by thermodynamic calculations to find a stainless grade promising a wear resistance equal to that of the standard cold work tool steel X153CrMoV12. It was shown that Nb is most suited to form MC carbides for wear resistance thus reducing the content of M7C3, which in turn raised the Cr content dissolved in the matrix to a passivating level. Small melts in the vicinity of steel X140CrNbMoTi15‐5‐2 confirmed this concept in respect to hardenability, wear resistance and corrosion resistance. Industrial manufacturing and application of the new grade RN15X® will be discussed.
