This SAE standard covers the minimum mechanical properties measured on separately cast test pieces of varying thickness and microstructural requirements for ductile iron castings used in automotive and allied industries. Castings may be specified in the as-cast or heat-treated condition. If castings are heat-treated, prior approval from the customer is required. The appendix provides general information on chemical composition, microstructure and casting mechanical properties, as well as other information for particular service conditions. In this standard SI units are primary and in-lb units are derived.

This SAE Standard covers the hardness, tensile strength, and microstructure and special requirements of gray iron sand molded castings used in the automotive and allied industries. Specific requirements are provided for hardness of castings. Test bar tensile strength/Brinell hardness (t/h) ratio requirements are provided to establish a consistent tensile strength-hardness relationship for each grade to facilitate prediction and control of tensile strength in castings. Provision is made for specification of special additional requirements of gray iron automotive castings where needed for particular applications and service conditions. NOTE—This document was revised in 1993 to provide grade specific t/h control. In 1999 the document was revised to make SI metric units primary.

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.

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 office 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. The steels listed in Tables 1 and 2 are no longer considered as standard steels. Producers should be contacted concerning availability.

This SAE Recommended Practice covers the mechanical and chemical requirements of the best quality hard drawn carbon steel spring wire used for the manufacture of engine valve springs and other springs requiring high fatigue properties. It also covers the basic material and processing requirements of springs fabricated from this wire.

This specification covers the mechanical and chemical requirements of hard drawn carbon steel spring wire in two classes used for the manufacture of mechanical springs and wire forms generally employed for applications subject to static loads or infrequent stress repetitions. This specification also covers basic material and processing requirements of the springs and forms fabricated therefrom. Class 2 is a higher tensile strength product and is furnished only when specified.

The scope of this SAE Information Report is to provide general information relative to the nature and use of infrared techniques for nondestructive testing. The document is not intended to provide detailed technical information, but will serve as an introduction to the theory and capabilities of infrared testing and as a guide to more extensive references.
