    Product Description :

    308 austenitic. Modified by extra Si and N2 for service temperature up to 1000 C.

    • Manufactured on an austenitic core wire of matching composition, the specially modified rutile flux has been metallurgically modified to ensure controlled levels of C-Si-N2.

    • The blend of silicates used during extrusion ensures both coating strength and a coating resistant to subsequent moisture absorption.

    Welding Features Of The Electrode :

    • Suitable for use on both AC and DC. Welds with a very stable, directional but low penetrating arc. Weld beads are exceptionally smooth and evenly rippled. Slag is normally self detaching and fillet welds slightly concave.

    • The slag is fairly fluid allowing full control of run-out length and the smaller diameters are suited for positional welding.

    Applications And Materials To Be Welded :

    • Intended / designed to weld similarly alloyed materials when both strength and

    • resistance to oxidation is required up to 1100 C.

    • Such wrought alloys are covered under ASTM / UNS S30815 and EN10095 1.4835

    • (21-11-2).

    • Proprietary alloys include AVESTA 253MA and the similarly alloyed AVESTA

    • 153MA as covered by ASTM UNS S30415.

    • Applications include furnace parts, high temperature flues, exhausts, combustion nozzles, etc.
