A-193 B7 is "killed" steel, fully deoxidized with Silicon. Regarding A-179 it need not be "killed"; however, if the original billets were continuously cast, as steelmaking stated, the tubes will have been fully deoxidized or "killed".

The chemical composition requirements for ASTM A 194 Grade 2H nuts specify a maximum of 0.4% Si, in accordance with Table 1. Fully killed steels usually contain 0.15% to 0.30% silicon - as long as silicon is not considered an alloying agent.
Review your CMTR's of the Grade 2H nuts to check for silicon content. CMTR's should be provided in accordance with 13.1 of ASTM A 194.
