Specification A542/A542Mincludes coverage of the material in the qu
4、enched-and-tempered condition.1.3 The maximum thickness of plates furnished to this specification is limited only by the capacity of the composition to meetthe specified property requirements. However, the maximum thickness of plates normally furnished under this specification is 6in. 150 mm.1.4 The
5、 material is intended to be suitable for fusion welding. Welding technique is of fundamental importance and it ispresupposed that welding procedures will be in accordance with approved methods.1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order spe

Within the text, the SI unitsare shown in brackets. The values stated in each sys
7、tem must be used independently of the other. Combining values from the twosystems may result in nonconformance with the specification.1.7 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for
