The information in this report covers data relating to SAE J438, Tool and Die Steels, and is intended as a guide to the selection of the steel best suited for the intended purpose and to provide recommended heat treatments and other data pertinent to their use. Specific requirements as to physical properties are not included because the majority of tool and die steels are either worked or given special heat treatments by the purchaser. The purchaser may or may not elect to use the accompanying data for specification purposes.

This Report presents general information on over 50 alloys in which nickel either predominates or is a significant alloying element. It covers primarily wrought materials, and is not necessarily all inclusive. Values given are in most cases average or nominal, and if more precise values are required the producer(s) should be contacted. This report does not cover the so-called "superalloys," or the iron base stainless steels. Refer to SAE J467, Special Purpose Alloys, and SAE J405, Chemical Compositions of SAE Wrought Stainless Steels, respectively, for data on these alloys.

The information and data contained in this SAE Information Report are intended as a guide in the selection of steel types and grades for various purposes. Consideration of the individual types of steel is preceded by a discussion of the factors affecting steel properties and characteristics. SAE steels are generally purchased on the basis of chemical composition requirements (SAE J403, J404, and J405). High-strength, low alloy (HSLA) steels (SAE J1392 and J1442) are generally purchased on the basis of mechanical properties; different chemical compositions are used to achieve the specified mechanical properties. Because these steels are characterized by their special mechanical properties obtained in the as-rolled condition, they are not intended for any heat treatment by the purchaser either before, during, or after fabrication. In many instances, as in the case of steels listed in SAE J1268 and J1868, hardenability is also a specification requirement.
