    Product Description :

    NO SPECIFICATION EXISTS BUT MAY BE COMPOSITIONALLY CODED AS 35Cr - 45Ni - Nb

    • Superaustenitic with superior resistance to carburisation and oxidation  at temperatures up to 1150 C

    • Manufactured on a high purity Cr-Ni wire, the chemically basic flux provides high resistance to microfissuring when welding thick sections and ensures low levels of non-metallic inclusions.

    • The flux is extruded on to the core wire using a blend of silicates that ensures both coating strength and a coating resistant to subsequent moisture absorption.

    Welding Features Of The Electrode :

    • Suitable for use on DC+ only, the arc is stable and directional but strike and restrikes should be made with the back-step technique. The weld beads are bright with fillet welds having a convex profile. Slag detachability is good even in thick

    • butt welds. Positional welding is best undertaken with 3.2mm and smaller diameters.

    • Metal recovery is some 130% with respect to weight of core wire

    Applications And Materials To Be Welded :

    This Alloy has superior resistance to carburisation and oxidation than those based

    on 25.35.HNb at temperatures up to 1150 C but creep strength is slightly lower.

    Applications occur mainly in the Petro Chemical Industry. Proprietary alloys

    include Lloyds T80 and T75 Ma (LBA)
