Tables 3A and 3B Removed reference maximum in Sulfur and Vanadium column titles, since ranges apply to these elements.1. SCOPEIn 1941, the SAE Iron and Steel Divi

9、sion, in collaboration with the American Iron and Steel Institute (AISI), made a major change in the method of expressing composition ranges for the SAE steels. The plan, as now applied, is based in general on narrower cast or heat analysis ranges plus certain product analysis allowances on individu

10、al samples, in place of the fixed ranges and limits without tolerances formerly provided for carbon and other elements in SAE steels.For years the variety of chemical compositions of steel has been a matter of concern in the steel industry. It was recognized that production of fewer grades of steel

11、could result in improved deliveries and provide a better opportunity to achieve advances in technology, manufacturing practices, and quality, and thus develop more fully the possibilities of application inherent in those grades.Comprehensive and impartial studies were directed toward determining whi

12、ch of the many grades being specified were the ones in most common demand, and the feasibility of combining compositions having like requirements. From these studies, the most common grades of steel have been selected and kept in the current revision. The cast or heat chemical composition limits or

13、ranges of these grades are given in Tables 1, 2, 3A, and 3B. These cast or heat limits or ranges are subject to standard variations for product analysis as given in SAE J409. Since AISI is no longer issuing steel grade designations, grades listed in this document are SAE grades.It is recognized that

14、 chemical compositions other than those listed in the previously mentioned tables will at times be needed for specialized applications or processing. When such a steel is required, the elements comprising the desired chemical composition are specified in one of three ways: (a) by a minimum limit, (b

15、) by a maximum limit, or (c) by minimum and maximum limits, termed a range.SAE INTERNATIONAL J403 Revised JUN2014 Page 2 of 11Standard cast or heat analysis limits and ranges for the various elements of carbon steels are given in Table 4. In this table, range is the arithmetical difference between t

16、he minimum and maximum limits (that is, 0.19 to 0.25 is a 0.06 range). These cast or heat limits and ranges are also subject to standard variations for product analysis as given in SAE J409.ISTC Division 1 has developed a procedure which allows for the maintenance of the grade lists in this document

17、. This will involve conducting an industry-wide survey to solicit input. This survey will be conducted at a frequency deemednecessary by the technical committee.Criteria have been established for the addition to or the deletion of grades from the grade lists. New grades will be considered based on t

18、he grade meeting a SAE grade designation and chemistry, having a minimum production or consumption of 225 tonnes/year (250 tons/year) and has the sponsorship of at least two individual users or producers. New steel compositions will be considered as Potential Standard (PS) steels, based on the guide

19、lines in SAE J1081, until such time as production of the new steel achieves a level of production or usage qualifying it for consideration as a standard steel.Deletion of grades will be by consensus based on the grade survey. Deleted grades will be archived in SAE J1249.When the cast or heat analysi

20、s is requested to be reported to demonstrate conformance to the chemical limits shown in Tables 1, 2, 3A, or 3B, in addition to the quantities of carbon, manganese, phosphorus, and sulfur, the following elements and their quantities shall also be reported: copper, chromium, nickel, molybdenum, and s

21、ilicon. When the amount of any one of these last five elements is less than 0.02% that analysis may be reported as “0.02%.”Based on a survey question in the 2006 Grade Survey, the grade lists have been revised such that chemistries of all product forms are now consolidated into single tables. The ch

22、emistry ranges listed will be the narrowest range for the various product forms with the exception of S content. It is acknowledged however that due to differences in the section size of the various product forms, chemical composition demands for the product forms should be different to allow for ad

23、equate flexibility of steel application. These differences are reflected in Tables 4 and 5.2.
