TENSAL-H4R

AWS: SFA 5.5 E9018-G H4R

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.

Precaution

1. Use short arc and stringer bead.

2. Re-dry the electrodes at 250°C for 1 hour, if expose to atmosphere.
