Medium and High Tensile Steel
ULTRATENSAL-69
AWS: SFA 5.5 E12018G H4
EN ISO CODE:
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. It is ideal for welding high strength low alloy steels used for sub- marine hull construction.
