ABRASIVE WEAR
1966-08-01
HISTORICAL
J965_196608
An enormous economic loss, as well as a waste of natural resources, is incurred world-wide as a result of wear of components and tools. Any effort expended in an attempt to reduce this loss is indeed worthwhile. The purpose of this SAE Information Report is to present the current state of knowledge of abrasive wear. This report, therefore, covers wear, or the undesired removal of metal by mechanical action, caused by abrasive particles in contact with the surface. It does not concern metal-to-metal wear or wear in the presence of an abrasive free lubricant. Abrasive wear occurs when hard particles, such as rocks, sand, or fragments of certain hard metals, slide or roll under pressure across a surface. This action tends to cut grooves across the metal surface, much like a cutting tool. Abrasive wear is of considerable importance in any part moving in relation to an abrasive.

AUTOMOTIVE METALLURGICAL JOINING
1970-10-01
HISTORICAL
J836_197010
This report is an abbreviated summary of metallurgical joining by welding, brazing, and soldering. It is generally intended to reflect current usage in the automotive industry; however, it does include some of the more recently developed processes. More comprehensive coverage of materials, processing details, and equipment required may be found in the Welding Handbook, Soldering Manual, and other publications of the American Welding Society and the American Society for Testing and Materials. AWS Automotive Welding Committee publications on Recommended Practices are particularly recommended for the design or product engineer. This report is not intended to cover mechanical joining such as rivets or screw fasteners, or chemical joining processes such as adhesive joining.

BEARING AND BUSHING ALLOYS
1991-10-01
HISTORICAL
J459_199110
The bearing performance of steel backed half bearings, bushings, and washers is dependent on the properties and thickness of the lining alloy, the strength and dimensional stability of the steel backing (usually SAE 1010) and the strength of the bond between the lining alloy and the backing. This SAE Information Report is primarily concerned with the properties of the lining alloys used in automotive applications, in particular, the crankshaft bearings of the internal combustion engine.

CLEANLINESS RATING OF STEELS BY THE MAGNETIC PARTICLE METHOD
1977-11-01
HISTORICAL
J421B_197711
This SAE Recommended Practice provides a rating procedure for the cleanliness rating of steels by the magnetic particle method. The procedure is based on counting the number of indications (frequency) and employs a weighted value to obtain a severity factor. The method outlined is similar to that described in SAE Aerospace Material Specification AMS 2301.

GENERAL CHARACTERISTICS AND HEAT TREATMENTS OF STEELS
1995-10-01
CURRENT
J412_199510
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.

High Temperature Materials for Exhaust Manifolds
1999-08-01
HISTORICAL
J2515_199908
A subcommittee within SAE ISTC Division 35 has written this report to provide automotive engineers and designers a basic understanding of the design considerations and high temperature material availability for exhaust manifold use. It is hoped that it will constitute a concise reference of the important characteristics of selected cast and wrought ferrous materials available for this application, as well as methods employed for manufacturing. The different types of manifolds used in current engine designs are discussed, along with their range of applicability. Finally, a general description of mechanical, chemical, and thermophysical properties of commonly-used alloys is provided, along with discussions on the importance of such properties.

Methods of Determining Hardenability of Steels
2009-03-27
HISTORICAL
J406_200903
This SAE Standard prescribes the procedure for making hardenability tests and recording results on shallow and medium hardening steels, but not deep hardening steels that will normally air harden. Included are procedures using the 25 mm (1 in) standard hardenability end-quench specimen for both medium and shallow hardening steels and subsize method for bars less than 32 mm (1-1/4 in) in diameter. Methods for determining case hardenability of carburized steels are given in SAE J1975. Any hardenability test made under other conditions than those given in this document will not be deemed standard and will be subject to agreement between supplier and user. Whenever check tests are made, all laboratories concerned must arrange to use the same alternate procedure with reference to test specimen and method of grinding for hardness testing.
