| Message: | SH.E7018 is a kind of carbon steel electrode with basic + ferrous powder coating, produced by import technology. Available for all position welding, all-current type (AC or DC). The coating is
resistant to moisture and the welding bead has good anti-cracking performance. The deposition
efficiency is around 120%.
Applicable for welding carbon steel, low alloy steel, steel for sheepbuilding and pressure
vessels.
