Washington Alloy, TE 7018 02HC, Welding Electrode, E7018; 1/8 in, Low Hydrogen, 50,000 psi Yield Strength

E7018 is the most efficient general-purpose, iron powder — low hydrogen electrode used for welding carbon steels, free-machining steels, and low alloy steels with a minimum yield strength of 50,000 psi. E7018 has a very good deposition rate, providing a quiet steady arc with low spatter and medium penetration. Weld deposits are of X-ray quality with easy slag removal, exceptional mechanical properties and a smooth uniform bead appearance. E7018 has excellent operator appeal and may be used in any position with AC or DC (reverse polarity).
