Standards

AWS/ASME SFA - 5.5 E9018M H4R

Properties And Applications

EM 174 is a low-hydrogen basic electrode designed for welding high-strength, low-alloy steels. The weld metal, with a tensile strength of 620 MPa (90 ksi), offers excellent toughness and crack resistance. Its specially formulated coating prevents moisture absorption, reducing the risk of hydrogen-induced cracking.It delivers outstanding results when welding high-strength steels such as T-1, HY-80, HY-90, and ASTM A514. With easy arc striking and restriking capabilities, it ensures reliable performance even under challenging conditions. The electrode provides high mechanical strength and radiographic quality in the as-welded condition, with no need for post-weld heat treatment, even at low temperatures.
