Categorization and Properties of Dent Resistant, High Strength, and Ultra High Strength Automotive Sheet Steel

1999-10-25
HISTORICAL
J2340_199910
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.

Properties of Low Carbon Sheet Steel and Their Relationship to Formability

1997-09-01
CURRENT
J877_199709
Problems associated with the evaluation of formability or deep drawability of sheet metals are complex and may be difficult to solve due to the number of variables involved. As long ago as 1940, the AISI Technical Committee on Sheet Steel reviewed this problem. More recently, Volume 1 of the Ninth Edition of the ASM Metals Handbook contains sections on 'Low Carbon Steel and Strip' and 'Formability of Steel Sheet' that provide suggestions to help evaluate parts and select materials. The purpose of this information report is to summarize the sheet metal characteristics that are commonly used when attempting to predict the formability of sheet metal.

CLASSIFICATION OF COMMON IMPERFECTIONS IN SHEET STEEL

CURRENT
J810_199603
Common or obvious surface imperfections, which sometimes occur in sheet steel, are normally visible to the naked eye before or after fabrication. Illustrations and definitions of these imperfections are contained in this SAE Information Report. The identifying names are those commonly used throughout the steel industry. The imperfections identified include the major and most often encountered imperfections known to exist at this time. These imperfections are variable in appearance and severity. Extreme conditions have been selected in some instances in order to obtain suitable photographs.

GLOSSARY OF CARBON STEEL SHEET AND STRIP TERMS

1994-10-01
HISTORICAL
J940_199410
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.

Standard Sheet Steel Thickness and Tolerances

1991-04-01
HISTORICAL
J1058_199104
This SAE Recommended Practice provides an orderly series for designating the thickness of uncoated and coated hot-rolled and cold-rolled sheet and strip. This document also provides methods for specifying thickness tolerances. Requirements of industry permit leeway in the choice of thickness in some instances, but it is recognized that for many applications, particularly the tonnage requirements of the mass production industries, thickness is normally determined by critical engineering design or manufacturing considerations. However, for general applications or where requirements permit some latitude in the selection of thickness, the preferred thickness given in Table 1 will facilitate interchangeability of different metals in design, reduce inventory, and increase the availability in warehouse stocks of thicknesses commonly required for general applications. All of the thicknesses listed are not necessarily produced in all metals and grades.

Method for Determining Breakage Allowances for Sheet Steel

1987-02-01
CURRENT
J424_198702
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. Breakage, for the purpose of this proposal, is defined as unrepairable parts, broken during forming and classed as scrap. Parts showing laminations, resulting from pipe, should be excluded provided they are separately identified. Broken parts which can be salvaged are not covered in this proposed method.

HISTORICAL
J126_198606
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. 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.
