Low Carbon and High Strength Steel SJ-50Y
Specification：AWS A5.18 ER70S-G
ISO 14341-A-G 424 C14Si1
GB/T8110-2020 ER50-G
DIN8559 SG3
Introduction：
Wide range of applications: suitable for welding low-carbon steel, low-alloy steel, and some medium-strength structural steel.
Good resistance to porosity: the addition of silicon and manganese helps reduce porosity defects in the weld.
Smooth feeding, stable arc, and beautiful weld bead appearance, low spatter,has excellent welding performance.
The deposited metal has good mechanical properties.
Application：
Automobiles
Shipbulding
Bridges
Constructions
Machinery
Pass the certification：
JIS、 CE
