SAE J402中描述的SAE钢材命名系统根据化学成分对钢材进行分类和编号。对于SAE J1442中的抗凹痕、高强度和超高强度钢，以及SAE J935中的高强度碳和合金模拉钢，最低机械性能要求已包含在名称中。此外，大多数合金钢和一些碳钢的淬透性数据将在SAE J1268中找到。

The SAE system of designating steels, described in SAE J402, classifies and numbers them according to chemical composition. In the case of the dent resistant, high strength and ultra high strength steels in SAE J1442 and the high strength carbon and alloy die drawn steels in SAE J935, minimum mechanical property requirements have been included in the designations. In addition, hardenability data on most of the alloy steels and some of the carbon steels will be found in SAE J1268.
