Washington Alloy, TC 70S-6 16, Welding Wire, ER70S-6; .045 in, 11 lb, 80,380 psi

ER70S-6 contains high levels of manganese and silicon for stronger deoxidizing power where stringent cleaning procedures are not possible. This wire has been designed to provide X-ray quality porosity-free welds and the highest tensile strength (as welded) of the plain carbon steel wires. The high silicon content increases the fluidity of the weld pool, creating a smoother bead appearance and resulting in minimal post-weld grinding. ER70S-6 is excellent where poor fit-ups or rusty and oily plates may be used
