STARBLAZE PRIME 9018 B92
AWS A5.5: E9018-B92 | EN ISO 3580-A: E Z CrMoWVNb9 0.5 2 B 42 H5
Tungsten Fortified Electrode, Superior Creep Strength, High Temperature Service up to 620°C
A basic coated low hydrogen tungsten-fortified electrode specially designed for welding advanced creep resistant steels operating at elevated temperatures up to +620°C. StarBlaze PRIME 9018-B92 provides improved creep strength, toughness, fatigue life, oxidation resistance, and corrosion resistance under prolonged high-temperature service. The weld metal contains chromium, molybdenum, tungsten, vanadium, niobium, and nitrogen additions to deliver exceptional mechanical properties for critical power generation applications. It offers excellent weldability, self-peeling slag, finely rippled weld beads, and radiographic quality weld deposits.
