Chemical compositions of virgin powder. All powders meet UNS S17400 according to ASTM A564/A564M - 19a [52]. Values are in mass fraction (%). Elements were measured using inductively coupled plasma (ICP) except for N and O which were measured using inert gas fusion and C and S which were measured using combustion analysis.
