Arc Welding Service

CATEGORY

TYPE

High-alloyed tubular wire based on Super Duplex low carbon deposit for the Sub-Arc process

APPLICATIONS

Welding forget or cast Super Duplex stainless steels for service in the as welded condition. For use where a high strength and good corrosion resistance is important in oil and gas production and processing system: pumps, valves, piping systems, risers etc.. SACW Super Duplex can also be used as an alternative for root welds to standard duplex to offer improved pitting resistance.

PROPERTIES

Higher productivity, higher deposition rates and improved wetting properties compared to solid wires with excellent X ray soundness. Improved hot cracking resistance and mechanical properties. To be used with welding flux FL 8111 or FL 838
