The principal application of Atom Arc 9018-CM electrodes is for welding 2.5% Cr - 1% Mo steels commonly found in pressure vessels, heat exchangers, pipings and other related components

• 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
