The purpose of this SAE Recommended Practice is to describe the terms yield strength and yield point. Included are definitions for both terms and recommendations for their use and application.
This standard covers the identification, classification, and chemical composition of tool and die steels for use by engineers, metallurgists, tool designers, tool room supervisors, heat treaters, and tool makers.

This SAE Recommended Practice describes a method for measuring Roughness Average (Ra) and Peak Count (PC) and other variables of the surface of metallic coated and uncoated steel sheet/strip.
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.
This SAE Recommended Practice covers seven levels of high strength carbon and low-alloy hot rolled sheet and strip, cold rolled sheet, and coated sheet steels. The strength is achieved through chemical composition and special processing.
These test procedures were developed based upon the knowledge that steel panel dent resistance characteristics are strain rate dependent. The “quasi-static” section of the procedure simulates real world dent phenomena that occur at low indenter velocities such as palm-printing, elbow marks, plant handling, etc. The indenter velocity specified in this section of the procedure is set to minimize material strain rate effects. The dynamic section of the procedure simulates loading conditions that occur at higher indenter velocities, such as hail impact, shopping carts, and door-to-door parking lot impact. Three dent test schedules are addressed in this procedure. Schedule A is for use with a specified laboratory prepared (generic) panel, Schedule B is for use with a formed automotive outer body panel or assembly, and Schedule C addresses end product or full vehicle testing.
This SAE Recommended Practice provides an orderly series for designating the thickness of unocated and coated hot-rolled and cold-rolled sheet and strip. This document also provides methods for specifying thickness tolerances.

The choice of the type and grade of solder for any specific purpose will depend on the materials to be joined and the method of applying. Those with higher amounts of tin usually wet and bond more readily and have a narrower semi-molten range than lower amounts of tin. For strictly economic reasons, it is recommended that the grade of solder metal be selected that contains least amount of tin required to give suitable flowing and adhesive qualities for application. All the lead-tin solders, with or without antimony, are usually suitable for joining steel and copper base alloys. For galvanized steel or zinc, only Class A solders should be used. Class B solders, containing antimony usually as a substitute for some of the tin or to increase strength and hardness of the filler metal, form intermetallic antimony-zinc compounds, causing the joint to become embrittled. Lead-tin solders are not recommended for joining aluminum, magnesium, or stainless steel.
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.
This SAE Recommended Practice defines the set-up and procedure for conducting the SAE Single Tooth Bending Fatigue Test. The details of the test fixture to be used (referred henceforth as “the test fixture” in this document) and gear test sample and the procedures for testing and analyzing the data are presented in this document.
Zinc and zinc-alloy coated steel is used to enhance a structure’s protection against corrosion degradation. For the purpose of this SAE Recommended Practice, a galvanized coating is defined as a zinc or zinc-alloy metallic coating. The selection of the optimum galvanized steel sheet product depends on many factors, the most important being: desired corrosion protection, formability, weldability, surface characteristics, and paintability. The trade-offs of these product characteristics are more complex than is the case with uncoated steel sheet products.
