Product Description

Acid Carbon Steel Electrodes

J422 According with GB E4303

Introduction: J422 is a kind of carbon steel electrode with Lime- titania type coating specially used for
facial  welding or  low- alloy steel/low mechanical property requirement steel as 09Mn2.
AC/DC. All-position welding. lt has glossy and beautiful appearance of weld ,excellent mechanical
properties. easy re-ignition,stable arc, good fluidity and detachability of slag.


Applications:Applicable for welding the structures with high appearance requirements,such as ocean
platforms,ships,vehicles,construction machinery,etc.
