See Table 1 for thick
4、nesses available in each grade.1.2 If the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use orservice will be utilized. See Appendix X 3 of Specification A6/A6M for information on weldability.1.3 The values stated in either inch-pound
5、units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be usedindependently of the other, without combining values in any way.2. Referenced Documents2.1
