Irrespective of being an Impact Testing Material, (depending on MDMT of the design code & Piping Classification info), A Number for 2% Ni Electrode E80S-NI2 is different from that of E70S2 QW-442 & SFA 5.28 & in reference to QW-256 & QW-404.5 it's an essential variable...So I believe it'll need requalification unless you could find another escape in the code.
