Medium and High Tensile Steel
ULTRATENSAL-MC
AWS: SFA 5.5 E10018M
EN ISO CODE:
Ultratensal- MC is a basic coated extra low hydrogen electrode. Weld metal displays excellent crack resistance and produces sound weld metal possessing excellent strength combined with good impact properties at sub zero temperature. It is ideally suited for welding high strength Q&T steels like WEL-TEN 80, WEL-TEN 690 RE-A, WEL TEN 690 RE-B, RDE-S-70, SA 517 grades and their equivalents. The electrodes are ideally suited for welding highly restrained joints in high strength steels under site conditions with high relative humidity since the extra low hydrogen content of the weld metal helps preventing hydrogen induced cracking.
