AWS E7018 carbon steel electrode

According with GB E5018
Corresponding with AWS E7018

Introduction: It is a kind of carbon steel electrode with iron powder low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The deposition efficiency is higher due to the iron powder in the coating. It has stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. The deposited metal has excellent mechanical properties.

Uses: Used for welding carbon and low-alloy steel structures, such as 16Mn, etc.
