Al2O3颗粒越多、间距越小，对疲劳性能危害越大。而易变形的硫化物和硅酸盐夹杂引起的裂纹少。关于Al2O3夹杂的临界尺寸，有文献指出，对于900型（b-880MPa）钢轨，Al2O3夹杂的累积长度为2mm时开始出现裂纹；对高度热处理轨（硬度＞351HB），累积长度从5mm开始出现裂纹。引起疲劳裂纹的单个夹杂颗粒的临界尺寸，在表层应力区为10m，在中心部位则为30m。此外，由于Al2O3夹杂对超声波的反射能力特别小，一般情况下用超声法检查不出来的，只有当它与硅酸盐、Fe(Mn)O及硫化物结合，或者当它与基体分离在界面产生裂缝时，才能用超声法检测出来。

与全淬透的gcr15钢轴承比较，gcr4钢轴承的寿数显着进步，可用于重载高速列车轴承。往后轴承钢首要向高洁净度和功能多样化两个方向开展。进步轴承钢的洁净度，特别是下降钢中的氧含量，能够显着延伸轴承的寿数。氧含量由28ppm下降到5ppm，疲惫寿数能够延伸1个数量级。为了延伸轴承钢的寿数，人们多年来一向致力于开发运用精粹技能来下降钢中的氧含量。经过不懈的尽力，轴承钢中的氧含量已从2世纪6时代的28ppm下降到9时代的5ppm。

典型的铁素体一珠光体耐热钢12Cr1MoV、2.25Cr1Mo、15CrMo、12Cr2MoWVSiTiB等中均含有钼。能够说，钼现已是耐热钢的根底合金元素了。～12%Cr型马氏体耐热钢中的首要强化相是MM23C6和M6C型碳化物。因为钢中存在钒和铌，部分钼和钨构成M23C6和M6C，大部分钼和钨溶于基体起固溶强化效果。而钢中钼和钨含量份额影响着钢的耐久强度。研讨标明，增加钼能够进步蠕变开裂强度。
