Low Hydrogen Potassium Coating Electrodes E-7016 of Superior Quality for Carbon Steel

E7016

AWS A5.1 E7016

Explain:

E7016 is a carbon steel electrode with low potassium content. AC and DC dual-use, can be carried out in all position welding. With good welding performance, stable arc, less spatter and easy slag removal, the deposited metal has excellent mechanical properties and crack resistance, low temperature impact toughness.

purpose:

Used for welding of medium carbon steel and low alloy steel structures, such as 16Mn, 09Mn2Si and marine A, B, D, E grade steel, etc., also used for thick plate and weldability of carbon steel structure welding.
