This SAE Information Report provides a uniform means of designating wrought steels during a period of usage prior to the time they meet the requirements for SAE standard steel designation. The numbers consist of the prefix PS1 followed by a sequential number starting with 1. A number once assigned is never assigned to any other composition. A PS number may be obtained for steel composition by submitting a written request to SAE Staff, indicating the chemical composition and other pertinent characteristics of the material. If the request is approved according to established procedures, SAE Staff will assign a PS number to the grade. This number will remain in effect until the grade meets the requirements for an SAE standard steel or the grade is discontinued according to established procedures. Table 1 is a listing of the chemical composition limits of potential standard steels which were considered active on the date of the last survey prior to the date of this report.

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.

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.

The scope of this SAE Information Report is to provide general information relative to the nature and use of magnetic particles 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 magnetic particle testing, and as a guide to more extensive references.

Hardness testing with files consists essentially of cutting or abrading the surface of metal parts, and approximating the hardness by the feel, or extent to which, the file bites into the surface. The term "file hard" means that the surface hardness of the parts tested is such that a new file of proven hardness will not cut the surface of the material being tested.

The purpose of this SAE Information Report is to provide general information relative to the nature and use of eddy current techniques for nondestructive testing. The document is not intended to provide detailed technical information but to serve as an introduction to the principles and capabilities of eddy current testing, and as a guide to more extensive references listed in Section 2.

This SAE Standard covers the mechanical and physical property requirements for Austempered Ductile Iron (ADI) castings used in automotive and allied industries. Specifically covered are: a Hardness b Tensile Strength c Yield Strength d Elongation e Modulus of Elasticity f Impact Energy g Microstructure In this document SI units are primary and in-lb units are derived.

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 Recommended Practice describes methods for determining plastic deformation encountered in the forming or drawing of sheet steel.

The SAE system of designating steels, described in SAE J402, classifies and numbers them according to chemical composition. In the case of the dent resistant, high strength and ultra high strength steels in SAE J2340, advanced high strength steels described in SAE J2745, and the high strength steels in SAE J1442 and the high-strength carbon and alloy die drawn steels in SAE J935, minimum mechanical property requirements have been included in the designations. In addition, hardenability data on most of the alloy steels and some of the carbon steels will be found in SAE J1268.

This SAE Recommended Practice is intended to provide basic information on properties and characteristics of high-strength carbon and alloy steels which have been subjected to special die drawing. This includes both cold drawing with heavier-than-normal drafts and die drawing at elevated temperatures.
