StarBlaze Prime 9018-G
AWS A5.5: E 9018-G
Superior Moisture Resistance | Low Hydrogen | Enhanced Weld Toughness
A low hydrogen, basic-coated electrode specially formulated for high tensile, fine-grained structural steels. Delivers excellent weldability in all positions, strong crack resistance, and stable arc performance. The deposited weld metal contains 0.4% Mo and 1% Ni, making it ideal for critical applications such as pressure vessels, boilers, power stations, and refinery equipment.
