J423

According with GB E4301

Introduction: J423 is a kind of carbon steel electrode with titania ferric type coating. AC/DC. Suitable for downhand welding and flat fillet welding. Its vertical weldability is a little worse than that of J422. It has stable arc, deeper penetration, good slag fluidity and detachability, and regular ripples..

Applications: Used for welding key low-carbon steel structures, such as vehicles, construction structures, heavy machinery structures, etc.
