Hydrogen Embrittlement Testing of Ultra High Strength Steels and Stampings by Acid Immersion

2023-03-08

CURRENT

J3215_202303

This standard describes a test method for evaluating the susceptibility of uncoated cold rolled and hot rolled Ultra High Strength Steels (UHSS) to hydrogen embrittlement. The thickness range of materials that can be evaluated is limited by the ability to bend and strain the material to the specified stress level in this specification. Hydrogen embrittlement can occur with any steel with a tensile strength greater than or equal to 980 MPa. Some steel microstructures, especially those with retained austenite, may be susceptible at lower tensile strengths under certain conditions. The presence of available hydrogen, combined with high stress levels in a part manufactured from high strength steel, are necessary precursors for hydrogen embrittlement. Due to the specific conditions that need to be present for hydrogen embrittlement to occur, cracking in this test does not indicate that parts made from that material would crack in an automotive environment.

Categorization and Properties of Steel Sheet for Automotive Cold Forming Applications

2022-04-01

CURRENT

J2947_202204

This SAE Recommended Practice establishes and defines requirements for grades of continuously cast automotive steel sheet that can be formed, welded, assembled, and painted in automotive manufacturing processes. These sheet steels can be specified as hot-rolled, cold-rolled, uncoated, or coated. Steel sheet can be coated by hot dipping, electroplating, or vapor deposition of zinc, aluminum, or organic compounds. Not all combinations of material types, strength levels, and coating types may be commercially available. Consult your steel supplier for availability.

Product Analysis - Permissible Variations from Specified Chemical Analysis of a Heat or Cast of Steel

2021-07-15

CURRENT

J409_202107

Supplementary to the heat or cast analysis, a product analysis may be made on steel in the semifinished or finished form. For definitions and methods of sampling steel for product chemical analysis, refer to SAE J408. A product analysis is a chemical analysis of the semifinished or finished steel to determine conformance to the specification requirements. The range of the specified chemical composition is normally expanded to take into account deviations associated with analytical reproducibility and the heterogeneity of the steel. Individual determinations may vary from the specified heat or cast analysis ranges or limits to the extent shown in Tables 1 through 5. The several determinations of any element in a heat or cast may not vary both above and below the specified range except for lead. Tables 1 through 5 provide permissible limits for various steel forms and composition types.

Glossary of Carbon Steel Sheet and Strip Terms

2019-07-29

CURRENT

J940_201907

This glossary is intended to provide engineers, metallurgists, and production personnel with uniform definitions of commonly used carbon sheet and strip terms. The glossary serves to supplement information and photographs reported in SAE J810, J763, J877, J863, and J403. Many of the terms listed apply only to hot-dipped zinc-coated products or to uncoated products. The letter C following the term identifies a term applying to coated materials, while the letters NC identify a term applying to uncoated materials. Where no identification is provided, the term is common to both.

Sintered Powder Metal Parts: Ferrous

2018-08-24

CURRENT

J471_201808

Powder metal (P/M) parts are manufactured by pressing metal powders to the required shape in a precision die and sintering to produce metallurgical bonds between the particles, thus generating the appropriate mechanical properties. The shape and mechanical properties of the part may be subsequently modified by repressing or by conventional methods such. as machining and/or heat treating. While powder metallurgy embraces a number of fields wherein metal powders may be used as raw materials, this standard is concerned primarily with information relating to mechanical components and bearings produced from iron-base materials.

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.

Hardness Tests and Hardness Number Conversions

2018-01-10

CURRENT

J417_201801

This report lists approximate hardness conversion values; test methods for Vickers Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Shore Hardness; and information regarding surface preparation, specimen thickness, effect of curved surfaces, and recommendations for Rockwell surface hardness testing for case hardened parts. The tables in this report give the approximate relationship of Vickers Brinell, Rockwell, and Scleroscope hardness values and corresponding approximate tensile strengths of steels. It is impossible to give exact relationships because of the inevitable influence of size, mass, composition, and method of heat treatment. Where more precise conversions are required, they should be developed specially for each steel composition, heat treatment, and part.

General Information - Chemical Compositions, Mechanical and Physical Properties of SAE Aluminum Casting Alloys

2018-01-10

CURRENT

J452_201801

The SAE Standards for aluminum casting alloys cover a wide range of castings for general and special use, but do not include all the alloys in commercial use. Over the years, aluminum alloys have been identified by many numbering systems as shown in Table 1. Presently, SAE is recommending the use of the UNS Numbering System to identify these materials. The castings are made principally by sand cast, permanent mold, or die cast methods; however, shell molding, investment casting, plaster cast, and other less common foundry methods may also be used. If the alloys listed do not have the desired characteristics, it is recommended that the manufacturers of aluminum castings be consulted.
