Super Duplex Steel Filler Wire are welded with Gas Tungsten Arc Welding (GTAW) process. Thorough cleaning of super duplex Steel welding wires after welding is essential to obtain good corrosion resistance. All slag and oxide on and around the weld must be removed. Super duplex steel filler wire is being used in different applications, such as for designed for welding ferritic–austenitic super duplex stainless.
Super duplex steel filler wire has a high level of nitrogen and chromium and a much higher level of pitting resistance, general corrosion, crevice and much more. The balanced dual-phase microstructure integrates high strength with cost-effective resistance to corrosion, especially in high chloride solutions. Super duplex steel filler wire provides better tolerance to stress corrosion cracking in chloride-bearing conditions, excellent pitting and crevice corrosion tolerance, and higher strength than most other steel forms.
Super duplex steel welding wire has greater corrosion tolerance, better mechanical properties and lower alloy cost. The unique characteristics of Super Duplex steel imply that it is in high demand for various scenarios in the oil and gas industry, petrochemical plants, chemical plants, industrial machinery, power industry, paper & pulp industry, food processing industry, refineries, utility and industrial systems, and high-strength wiring solutions.
Super duplex filler wire has high thermal conductivity and low thermal expansion compared to conventional austenitic stainless steel. Super duplex rods are suitable for air and oil hardening and offer high hardness maintenance.
