適用范圍：This SAE Information Report provides a list of those SAE steels which, because of decreased usage, have been deleted from the standard SAE Handbook listings. Included are alloy steels from SAE J778 deleted since 1936, carbon steels from SAE J118 deleted since 1952, and all Ex-steels deleted from SAE J1081. Information concerning SAE steels prior to these dates may be obtained from the SAE offices on request. With the issuance of this report, SAE J778, Formerly Standard SAE Alloy steels, and SAE J118, Formerly Standard SAE Carbon Steels, will be retired since they are now combined in SAE J1249. In the future, new assignments to SAE J1081, Chemical Compositions of SAE Experimental Steels, will be given PS (Potential Standard) numbers rather than EX numbers.
