Atom Arc 8018-CM electrodes contain 1.25% Cr and 0.50% Mo as alloy addition. They are used for the welding of such steels as 0.5% Cr - 0.5% Mo, 1% Cr - 0.5% Mo, and 1.25% Cr - 0.5% Mo, which are used principally in power piping and boiler work for the fabrication of plates, pipes, tubes, castings, and forgings

• Moisture resistant coatings are incorporated in all AtomArc® electrodes
• The flux coatings are manufactured to effectively resist moisture pick-up in opened containers
• The improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
• Flat, horizontal, vertical up, overhead welding positions
• Medium penetration
• 2.6 lb/hr at 120 amp, 2.7 lb/hr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency
