潜在的标准钢

[中文适用范围]： 本 SAE 信息报告提供了在锻钢满足 SAE 标准钢名称要求之前的使用期间对其进行指定的统一方法。这些数字由前缀 PS1 后跟从 1 开始的连续数字组成。数字一旦分配，就永远不会分配给任何其他组合。通过向 SAE 工作人员提交书面请求，可以获取钢成分的 PS 编号，其中注明材料的化学成分和其他相关特性。如果请求根据既定程序获得批准，SAE 工作人员将为该等级分配一个 PS 编号。该编号将一直有效，直到该牌号满足 SAE 标准钢的要求或该牌号根据既定程序停产。表 1 列出了潜在标准钢的化学成分限制，这些标准钢在本报告日期之前的最后一次调查日期被认为是有效的。 [外文原描述]： This SAE Information Report provides a uniform means of designating wrought steels during a period of usage prior to the time they meet the requirements for SAE standard steel designation. The numbers consist of the prefix PS 2x followed by a sequential number starting with 1. A number once assigned is never assigned to any other composition.A PS number may be obtained for steel composition by submitting a written request to SAE Staff, indicating the chemical composition and other pertinent characteristics of the material. If the request is approved according to established procedures, SAE Staff will assign a PS number to the grade. This number will remain in effect until the grade meets the requirements for an SAE standard steel or the grade is discontinued according to established procedures.Table 1 is a listing of the chemical composition limits of potential standard steels which were considered active on the date of the last survey prior to the date of this report. These ladle limits are subject to standard variations for check analysis as given in SAE J409.Cross Reference: J409_202107
