见ASME II-D 1A注(g)
(g) Where specifications, grades, classes, and types are listed in this Table, and where the material specification in Section II, Part A or
Part B is a dual-unit specification (e.g., SA-516/SA-516M), the values listed in this Table shall be applicable to either the customary
U.S. version of the material specification or the SI units version of the material specification. For example, the values listed for SA-516
Grade 70 shall be used when SA-516M Grade 485 is used in construction.
所以说。。。SA-516 Grade 485这个标注,是错误的 |
