J401_201203
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 Information Report relates to hot-rolled steel bar products. It is intended as a guideline to assist in the selection and specification of hot-rolled steel bar; however, it is not to be interpreted as a material specification in itself.

Restricted Hardenability Bands for Selected Alloy Steels

2010-02-15
CURRENT
J1868_201002
Restricted hardenability steels have been in use for some time but the specific restrictions for a particular grade depend upon customer needs and vary from mill to mill. Such steels are desirable to provide more controlled heat treatment response and dimensional control for critical parts. Because of increasing interest in steels with restricted hardenability, the SAE Iron and Steel Technical Committee directed Division 8 to prepare a set of standard steels with restricted hardenability. In 1993, the American Society for Testing and Materials (ASTM) adopted the twelve SAE restricted hardenability steels and added ten more. SAE decided to include in SAE J1868 the additional 10 steels. In general, steels with restricted hardenability (RH steels) will exhibit a hardness range not greater than 5 HRC at the initial position on the end-quench hardenability bar and not greater than 65% of the hardness range for standard H-band steels (see SAE J1268) in the "inflection" region.

Potential Standard Steels

CURRENT
J1081_200011
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.

PRODUCT ANALYSIS—PERMISSIBLE VARIATIONS FROM SPECIFIED CHEMICAL ANALYSIS OF A HEAT OR CAST OF STEEL

1995-02-01
CURRENT
J409_199502
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.

New Steel Designation System for Wrought or Rolled Steel

2005-07-20
CURRENT
J402_200507
This SAE Standard describes a new alphanumeric designation system for wrought steel used to designate wrought ferrous materials, identify chemical composition, and any other requirements listed in SAE Standards and Recommended Practices. The previous SAE steel designation coding system consisted of four or five numbers used to designate standard carbon and alloy steels specified to chemical composition ranges. Using SAE 1035 as an example, the 35 represents the nominal weight % carbon content for the grade. Using SAE 52100 as an example, the 100 represents the nominal weight % carbon content. The first two numbers of this four or five number series are used to designate the steel grade carbon or alloy system with variations in elements other than carbon. These are described in Table 1. In addition to the standard four or five number steel designation above, a letter was sometimes added to the grade code to denote a non-standard specific element being added to the standard grade.

Methods of Determining Hardenability of Steels

2009-03-27
CURRENT
J406_200903
This SAE Standard prescribes the procedure for making hardenability tests and recording results on shallow and medium hardening steels, but not deep hardening steels that will normally air harden. Included are procedures using the 25 mm (1 in) standard hardenability end-quench specimen for both medium and shallow hardening steels and subsize method for bars less than 32 mm (1-1/4 in) in diameter. Methods for determining case hardenability of carburized steels are given in SAE J1975. Any hardenability test made under other conditions than those given in this document will not be deemed standard and will be subject to agreement between supplier and user. Whenever check tests are made, all laboratories concerned must arrange to use the same alternate procedure with reference to test specimen and method of grinding for hardness testing.

Mechanical Properties of Heat Treated Wrought Steels

CURRENT
J413_201110
The figures in this SAE Information Report illustrate the principle that, regardless of composition, steels of the same cross-sectional hardness produced by tempering after through hardening will have approximately the same longitudinal1 tensile strength at room temperature. Figure 1 shows the relation between hardness and longitudinal tensile strength of 0.30 to 0.50% carbon steels in the fully hardened and tempered, as rolled, normalized, and annealed conditions. Figure 2 showing the relation between longitudinal tensile strength and yield strength, and Figure 3 illustrating longitudinal tensile strength versus reduction of area, are typical of steels in the quenched and tempered condition. Figure 3 shows the direct relationship between ductility and hardness and illustrates the fact that the reduction of area decreases as hardness increases, and that, for a given hardness, the reduction of area is generally higher for alloy steels than for plain carbon steels.
