A SUPER DUPLEX TIG WIRE WITH COPPER FOR WELDING
SUPER DUPLEX ALLOYS OF SIMILAR COMPOSITION.
GM 2553 is designed to weld similar alloys usually supplied as castings. The addition of copper improves corrosion resistance in sulphuric acid media and also increase strength and wear resistance. The electrode gives matching strength and corrosion resistance in the solution treated condition but can also be used in the as-welded condition. Nitrogen and nickel contents are controlled to give a balanced duplex structure to minimise the risk of cracking, particularly in highly restrained welds.
Pumps and valves, corrosion/ wear resisting parts and process equipment for use in offshore oil and gas industries, pulp, paper and textile industries, and chemical and petrochemical plant.
