Medium and High Tensile Steel
TENSAL-H4R
AWS: SFA 5.5 E9018-G H4R
EN ISO CODE:
Tensal-H4R is basic coated, extra low hydrogen, moisture resistance type electrode for welding high strength steels. It is suited for welding steels having tensile strength up to 690 MPa. The weld metal possesses excellent toughness at sub-zero temperatures down to minus 50 C. Typical applications include welding of grain- refined steels, Q&T steels, HSLA steels, pressure vessels, structural fabrication, bridges, penstocks, tanks, etc.
