Technical Data Sheet

Chemical Composition Limits
Weight%	C	Mn	Si	P	S	Ni	Cr	Mo	V	Cu

Alloy ER 70S-6 contains high levels of manganese and silicon for stronger deoxidizing power where stringent cleaning procedures are not possible. The high silicon content increase the fluidity of the weld pool, creating a smoother bead appearance and resulting in minimal post-weld grinding. The Alloy ER70S-6 has been designed to provide X-ray quality porosity-free welds and the highest tensile strength (as welded) of the plain carbon steel wires. This wire is excellent where poor fit-ups or rusty and oily plates may be used. Some typical applications are truck bodies, farm implements, steel castings or forgings, shaft build ups and general shop fabrications.
