Looking at the query again, perhaps the user meant "ASTM A100-17" or another standard. Alternatively, "D100-17" could refer to a document from a different organization. Since the user mentioned "steel," maybe it's a welding standard? For example, ASTM E17 could be a standard, but that doesn't align. Wait, maybe the user is referring to the AISI (American Iron and Steel Institute) standard, but AISI typically deals with cold-formed steel structures, not technical specifications for steel grades.
