1.1 This standard provides a guide to ASTM Subcommittees A01.02, A01.03, A01.06, A01.09, A01.11, A01.15, A01.19, A01.22, and A01.28 for specifying chemical composition limits of wrought carbon, low-alloy, and alloy steels. It is intended that these recommended grade composition limits be suitable for adoption by other standardization bodies that prepare standards for carbon, low-alloy, and alloy steel products, including discontinued steels.<\/p>\n
1.2 Included in this guide are the recommendations for determining the number of significant figures for specifying chemical composition.<\/p>\n
1.3 The carbon and alloy steel grades in all standards overseen by the aforementioned ASTM subcommittees have been included, except those grades applicable to restricted special end uses.<\/p>\n
1.4 Not addressed are minor composition modifications that a specific ASTM subcommittee may find necessary to accommodate effects of normal processing or to enhance fabricability by the producer or user, or both.<\/p>\n
1.5 Also not generally addressed (except where established by ASTM 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.<\/p>\n
1.6 This guide does not address discontinued or formerly standard steel grades. A listing of such steel grades can be found in SAE J 1249. Also excluded from this guide are cast materials and welding filler metals.<\/p>\n
