Ferralium 255 Welding Wire (S32550)

Ferralium^® 255 – SD50 is produced to complement our leading range of super duplex 255 stainless steels. Careful formulation of the weld wire composition ensures the optimum combination of weld strength and corrosion resistance, achieved by over-alloying the wire with nickel to maintain the correct (austenite / ferrite) phase balance.
