Properties and Applications

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