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

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
