Properties And Applications

Basic type electrode for welding high temperature creep, oxidation and fatigue resistant steels, 9Cr-1Mo-V-Nb-N steels with operating temperatures of up to 650°C. Suitable for welding in piping and equipment production from P91, F91 and T91 with thin and thick walled and casting successfully, especially in power plants, chemical and petrochemical industry. Welds are X-ray quality.
