1941年，SAE钢铁部门与美国钢铁协会（AISI）合作，对表达SAE钢成分范围的方法进行了重大改变。目前采用的计划通常基于较窄的钢包分析范围加上个别样品的某些产品（检查）分析余量，以取代之前为SAE钢中的碳和其他元素提供的固定范围和无公差限值（参考SAE J408）。ISTC第1部分制定了一个程序，允许维护本SAE标准中的等级列表。这将包括进行一次全行业的调查，以征求意见。 该调查将以技术委员会认为必要的频率进行。已经制定了从成绩表中添加或删除成绩的标准。如果新牌号符合标准SAE牌号范围，最低使用量或产量为225吨/年（250吨/年），并得到至少两个用户或生产商的认可，则将考虑使用新牌号。根据SAE J1081中提供的指南，新钢成分仍将被视为潜在标准（PS）钢，直到新钢的生产或使用达到标准钢的生产或使用水平。 从成绩表中删除成绩将基于成绩调查结果达成共识。删除的等级将存档在SAE J1249中，以备将来参考。本文件中的成分可适用于平炉和碱性氧气或电炉钢。表1中带有前缀字母E的等级通常由电炉工艺制成，最大磷含量为0.025%，硫含量为0.025%。表1中给出的成分的标称化学极限或范围受SAE J409中给出的检查分析标准变化的影响。由于AISI不再发布钢材牌号，本文件中列出的所有牌号均为SAE牌号。

In 1941, the SAE Iron and Steel Division in collaboration with the American Iron and Steel Institute (AISI) made a major change in the method of expressing composition ranges for the SAE steels. The plan, as now applied, is based in general on narrower ladle analysis ranges plus certain product (check) analysis allowances on individual samples, in place of the fixed ranges and limits without tolerances formerly provided for carbon and other elements in SAE steels (reference SAE J408).ISTC Division 1 has developed a procedure which allows for the maintenance of the grade list in this SAE Standard. This will involve conducting an industry-wide survey to solicit input. This survey will be conducted at a frequency deemed necessary by the technical committee. Criteria have been established for the addition to or deletion of grades from the grade table. A new grade will be considered if it meets standard SAE grade ranges, has a minimum usage or production of 225 tonnes/year (250 tons/year), and has the endorsement of at least two users or producers. New steel compositions will still be considered as Potential Standard (PS) steels, based on the guidelines provided in SAE J1081, until such time as production of the new steel achieves a level of production or usage qualifying it for consideration as a standard steel.The deletion of a grade from the grade table will be by consensus based on the grade survey results. Deleted grades will be archived in SAE J1249 for future reference.The compositions in this document may apply to open hearth and basic oxygen, or electric furnace steels. Grades shown in Table 1 with prefix letter E are normally made by the electric furnace process with maximum limits of 0.025% phosphorus and 0.025% sulfur. The nominal chemical limits or ranges in the compositions given in Table 1 are subject to standard variations in check analysis given in SAE J409. Since AISI is no longer issuing steel grade designations, all grades listed in this document are SAE grades.
