Product Description

AWS EM12K
Submerged Arc Welding Wire
AWS A5.17 EM12K EN 756 S2Si

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.

Application: Matched with agglomerated flux SJ301(AWS F7A0-EM12K) or agglomerated flux SJ101(AWS F7A4-EM12K). Used for fabricating normal strength structures made by450-500MPa grade base metals.Like boilers, high pressure vessels, LGP, cylinder.
