ER70S-6 contains high levels of Manganese and Silicon which provide porosity-free welds and the highest tensile strength (as welded) of the plain carbon steel wires.

The high Silicon content increases fluidity of the weld pool, creating a smoother appearance and resulting in minimal post-weld grinding.

ER70S-6 is excellent where poor fit-ups or rusty, oily steel are used.

Tensile strength: 90,000 psi.

Elongation is 25%.
