and what about them? Is it a requirment? Should SA-20 be adhered to as well as the product spec? i thought that sa-20 covered a large range of general requirments? MDK
SA20 does cover a large range of general requirements, one of which is the limits on unspecified elements. SA20 is referenced in SA516 and is a requirement to be met by any spec that references it.
Depends on how the question was worded. If it asked what amount of nickel is "allowed" by SA516 for Grade 70 material, I would mark it correct. If the question is what amount of nickel is "specified" by SA516 for Grade 70, the answer is "none".
