Medium and High Tensile Steel
ULTRATENSAL-MH
AWS: SFA 5.5 E11018M
EN ISO CODE: 18275-B E 76 18 N4M2 A H5
Basic coated, extra low hydrogen electrode ideally suited for welding high strength Q&T steels like Welten 80, SA517 grades and their equivalents. The weld metal has excellent crack resistance and displays high strength combined with good sub-zero impact strength. Ideal for welding high strength steels under site conditions having high relative humidity and higher joint restraints as the extra low hydrogen levels ensure freedom from hydrogen induced cracking.
