J424

According with GB E4320
Corresponding with AWS  E6020


Introduction: J424 is a kind of carbon steel electrode with ferric oxide type coating. AC/DC. Used for downhand welding and flat fillet welding. The characteristics of this kind of electrode are its deep penetration, high melting rate and better hot cracking resistance due to its higher manganese content.


Uses: Able to weld key low-carbon structures, such as heavy machinery, construction machinery, etc.
