It is intended that these recommendedgrade composition limits be suitable for adoption by ot
4、her standardization bodies that prepare standards for carbon, low-alloy, andalloy steel products, including discontinued steels.1.2 Included in this guide are the recommendations for determining the number of significant figures for specifying chemicalcomposition.1.3 The carbon and alloy steel grade
5、s in all standards overseen by the aforementioned ASTM subcommittees have beenincluded, except those grades applicable to restricted special end uses.1.4 Not addressed are minor composition modifications that a specific ASTM subcommittee may find necessary toaccommodate effects of normal processing
6、or to enhance fabricability by the producer or user, or both.1.5 Also not generally addressed (except where established byASTM subcommittees) is a complete rationalization of all limits,especially where such would conflict with long-standing practices and is not justified by special technical effect
7、.1.6 This guide does not address discontinued or formerly standard steel grades. A listing of such steel grades can be found inSAE J1249. Also excluded from this guide are cast materials and welding filler metals.1.7 In 1995, the AISI made the decision to transfer the responsibility of maintaining i
8、ts numbering system to the Society ofAutomotive Engineers (SAE) for carbon and alloy steels (SAE J403 and SAE J404) and toASTM International for stainless steels(Guide A959 and others). To inform users of this important event, historical information is included in the appendix of thisstandard.1.8 Th
9、e values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.9 This international standard was developed in accordance with internationally recogniz

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 long product, ngeneric term describing wrought bars, rod, wire, rail, tubing (welded and seamless), plate, and pipe.3.1.1.1 DiscussionProduct forms such as “C” shapes, “HP” shapes, “L”
18、 shapes, “M” shapes, “MC” shapes, “S” shapes, “W” shapes, and sheet pilingare considered long products. Such product forms are produced to mechanical properties and are not normally produced to thechemical compositions listed in this guide.3.1.2 flat product, ngeneric term describing wrought sheet a
19、nd strip.3.2 Refer to Terminology A941 for additional definitions of terms used in this guide.4. 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 this gui
20、de for the grades identified in their product specifications unlessthere is a specific technical justification for doing otherwise.4.2 The composition limits given in this guide are to be used as guides in determining limits for each of the elements includedin the total composition of each grade. Th
21、e composition limits have been established with the intent that eachASTM subcommitteewill find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 lists the generalguidelines followed for determining the limits for each element; the limits establ
22、ished in this guide are based upon these guidelines.5. General Guidelines Used for Determining Composition Limits5.1 Table 1 gives typical chemical composition limits for respective elements.6.
