ER70S-6 Bare
AWS A5.18 ER70S-6 | ASME SFA 5.18 ER70S-6
This 70S-6 Bare is a non-copper coated carbon steel that contains high-levels of maganese and silicon for stronger deoxidizing power while having excellent welding results at optimal control at high welding speeds and amperage found in robotics or automation.
Applications:
Found in structural carbon steel pipeline/fitting, automotive, pressure low fume, low spatter, reduced copper fumes and less heat build up in excess long liners
