ATOM ARC 7018-Mo
Atom Arc 7018-Mo is an all-position low hydrogen electrode recommended for welding low-alloy, high tensile steels and 0.5% Mo steels. This rod is ideal for fabrication and erection of boilers pressure piping and tubing and other pressure vessel applications.
Features
Atom Arc 7018-Mo electrodes contain 0.5% Mo as alloy addition. They are recommended for welding low-alloy, high tensile steels of 50 ksi (345 MPa) minimum yield strength and also 0.5% Molybdenum steels and pipes. They are widely employed in the fabrication and erection of boilers, pressure piping and tubing and other pressure vessel applications.
