7、igh-strengthlow-alloy steel. Grade 50W 345W is manufactured fromhigh-strength low-alloy steel with enhanced atmospheric cor-rosion resistance. (See 10.1.2) The Grades may not be inter-changed without approval of the purchaser. ASTM Specifica-tions for plate that may be applied to Grade 50 345 and 50
8、W345W are listed in Reference Documents and in Table 1.1.5 This specification is expressed in both inch-pound unitsand in SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units),the inch-pound units shall apply. The values stated in eit
9、her SIunits or inch-pound units are to be regarded separately asstandard. Within the text, the SI units are shown in brackets.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
10、 in noncon-formance with the standard.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
