See  and  for descriptions of applicable remelting processes. 1.3 This practice and the accompanying comparison macrographs are generally applicable to steel bar and billet sizes up to 225 in.2  [1450 cm2] in transverse cross section.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.【中国标准分类号】: H44【国际标准分类号】: 77_140_60【页数】: 15P.;A4【正文语种】:
