ATOM ARC 8018-N
Atom Arc 8018-N is an all-position low hydrogen electrode that deposits weld metal with 3% Ni content. This electrode is used when low temperature notch toughness values are required.
Features
Atom Arc 8018-N electrodes produce excellent weld properties and are used to fabricate components where low temperature notch toughness values are required. Atom Arc 8018-N is also recommended for welding the 2% to 4% Ni steels.
