EM12K

According with GB H08MnA
Corresponding with AWS EM12K

Introduction: It is a kind of medium-manganese and medium-silicon type welding wire. It matches with medium-manganese and medium-silicon type welding flux. It is not sensitive to the rust on the base metal. It has excellent bead molding and slag detachability. Monopole or dipole. AC/DC.

Applications: Used together with fused flux 350 or sintered flux 101. Used for both high speed welding and filling welding on 50kg class base metals.
