ER70S-6
AWS A5.18 ER70S-6
ASME SFA 5.18 ER70S-6
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.
Applications:
Construction work, tanks, truck bodies, farm implements, pipes, steel castings or forgings, shaft build-ups and general shop fabrications.
