[SAW] H08MnA GB SU26 AWS EM12 2.5/3.2/4.0/5.0mm Insensitive To Rust On The Base Metal
Em12k Saw Wire Electrode AWS Em12 Em12k Welding Wire
Em12 2.5/3.2/4.0/5.0mm Submerged Arc Welding Wire
Submerged arc welding wire AWS EM12, 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. The wire can be applied single or dual feeding with AC/DC.
LT·H08MnA Conform to Standard :GB/T 5293 H08MnA
AWS Em12
ISO 14171-B-SU22
Purpose:Using with sintered flux LT•SJ101 , it can be applied both for high-speed welding steel plate of tensile strength 420N/mm2 and filling welding
