Product Catalog
Executive 2594 Super Duplex welding wire is designed to provide clean and consistent welds with excellent feedability and minimal clean-up. By maintaining tight control from the country of melt to the design of the spool Executive wire provides welders with the highest quality stainless bare wire.
Executive 2594 is over-alloyed 2-3% in nickel to provide optimum ferrite-austenite ratio in the finished weld.
Executive 2594 provides matching chemistry and mechanical property characteristics to wrought super-duplex alloys such as 2507 and Zeron 100 as well as super-duplex casting alloys.
Application and Features
Executive 2594 has high tensile and yield strength with superior resistance to stress corrosion, cracking (SCC) and pitting corrosion. It is suitable for pumps and valves, pressure vessels and process pipework. Executive 2594 is also used in aeronautic manufacturing, pressure piping, pumps and valves, vessel manufacturing, cladding, and general manufacturing and fabrication.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
