This SAE recommended practice defines and establishes tolerances and attributes of cold rolled strip steels. Differences between cold rolled strip and cold rolled sheet products are discussed so that process designers can make informed material selection decisions.

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.

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 defines and establishes mechanical property ranges for seven grades of continuously cast high strength automotive sheet steels that can be formed, welded, assembled, and painted in automotive manufacturing processes. The grade of steel specified for an identified part should be based on part requirements (configuration and strength) as well as formability. Material selection should also take into consideration the amount of strain induced by forming and the impact strain has on the strength achieved in the finished part. These steels can be specified as hot-rolled sheet, cold-reduced sheet, uncoated, or coated by hot dipping, electroplating, or vapor deposition of zinc, aluminum, and organic compounds normally applied by coil coating. The grades and strength levels are achieved through chemical composition and special processing. Not all combinations of strength and coating types may be commercially available. Consult your steel supplier for details.

This SAE Recommended Practice establishes mechanical property ranges for low-carbon automotive hot-rolled sheet, cold-rolled sheet, and metallic-coated sheet steels. It also contains information that explains the different nomenclature used with these steels.

This SAE Recommended Practice establishes a nomenclature for categorizing low carbon automotive hot rolled sheet, cold rolled sheet, and zinc and zinc alloy coated sheets.

The purpose of this SAE Information Report is to describe those properties of galvanized low carbon sheet steel which relate to its formability; that is, its ability to be formed with the structural, dimensional and surface integrity to fulfill the design intent.

This method is recommended for establishing breakage allowances for parts fabricated from cut lengths or blanks, or from coils processed directly into a progressive-die pressline, and is equitable to both the sheet producer and the fabricator.

This SAE Recommended Practice describes a method for measuring the surface texture of cold rolled, matte finish sheet steel with a roughness average (Ra) of 20–80 μ in.

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

This SAE Recommended Practice outlines a procedure for selecting the proper specification for carbon steel sheet and strip which are purchased to make an identified part. Specifications considered are: It also describes how codes or symbols for specifying certain characteristics may be used in electronic data processing systems. Characteristics covered are: a Hot or cold rolled. b Sheet or strip. c Severity of draw (quality of steel). d Surface condition (finish, etc.). e Edge condition. f Dimensions. It is intended that other characteristics and part identification be covered by a supplement to the specification, as necessary.
