1、Designation: A1040 17Standard Guide forSpecifying Harmonized Standard Grade Compositions forWrought Carbon, Low-Alloy, and Alloy Steels1This standard is issued under the fixed designation A1040; the number immediately following the designation indicates the year oforiginal adoption or, in the case o

2、f revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This guide covers ASTM Subcommittees A01.02,A01.03,A01.06,A01.09,A01.11,A01.15,A01.19,A01.22,

3、 andA01.28 for specifying chemical composition limits of wroughtcarbon, low-alloy, and alloy steels. It is intended that theserecommended grade composition limits be suitable for adop-tion by other standardization bodies that prepare standards forcarbon, low-alloy, and alloy steel products, includin

4、g discon-tinued steels.1.2 Included in this guide are the recommendations fordetermining the number of significant figures for specifyingchemical composition.1.3 The carbon and alloy steel grades in all standardsoverseen by the aforementioned ASTM subcommittees havebeen included, except those grades

5、 applicable to restrictedspecial end uses.1.4 Not addressed are minor composition modifications thata specific ASTM subcommittee may find necessary to accom-modate effects of normal processing or to enhance fabricabilityby the producer or user, or both.1.5 Also not generally addressed (except where

6、establishedby ASTM subcommittees) is a complete rationalization of alllimits, especially where such would conflict with long-standingpractices and is not justified by special technical effect.1.6 This guide does not address discontinued or formerlystandard steel grades. A listing of such steel grade

7、s can befound in SAE J1249. Also excluded from this guide are castmaterials and welding filler metals.1.7 In 1995, the AISI made the decision to transfer theresponsibility of maintaining its numbering system to theSociety of Automotive Engineers (SAE) for carbon and alloysteels (SAE J403 and SAE J40

8、4) and to ASTM Internationalfor stainless steels (Guide A959 and others). To inform users ofthis important event, historical information is included in theappendix of this standard.1.8 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematic

Significance and Use4.1 It is anticipated that the ASTM Subcommittees A01.02,A01.03,A01.06,A01.09,A01.11,A01.15,A01.19,A01.22, andA01.28 will use the standard composition limits listed in thisguide for the grades

19、identified in their product specificationsunless there is a specific technical justification for doingotherwise.4.2 The composition limits given in this guide are to be usedas guides in determining limits for each of the elementsincluded in the total composition of each grade. The compo-sition limit

20、s have been established with the intent that eachASTM subcommittee will find it necessary to require only aminimum number of changes to reflect specific technicaleffects. Section 5 lists the general guidelines followed fordetermining the limits for each element; the limits establishedin this guide a

Harmonized Standard Grade Wrought Carbon, Low-Alloy, and Alloy Steel Compositions6.1 The harmonized composition limits are given

22、in Tables2-17, grouped by metallurgical classification. Within all tables,grades are listed in numerical order.6.2 Unless adopted by the appropriate product subcommit-tee in an ASTM standard, the compositions described in thisguide shall not be used for specifying an ASTM product.6.3 Criteria for th
