SUPRATHERME-Ni
AWS: SFA 5.5 E7018-G
EN ISO CODE:
A low hydrogen, iron powder type electrode yielding a 0.5% Ni in the weld metal. Ideally suited for welding fine-grained steels, heavy sections, and restrained joints requiring good impact strength at sub-zero temperatures down to minus 50°C. Typical applications include welding of C-Mn grain refined steels, heavy sections, and restrained joints requiring good impact strength at sub-zero temperatures o down to minus 50°C.
