Ferralium 255
Super Duplex Stainless steel round bar

FERRALIUM 255 is a super duplex alloy with a high strength to weight ratio with superior abrasion and cavitation resistance. Resistance to chloride SCC, as well as crevice corrosion and pitting. Good ductility with a high fatigue strength in marine applications. Twice the yield strength of Alloy 20, and stronger than Duplex 2205. An excellent 40°C critical pitting temperature (ASTM G48-Method A), twice that of Alloy 2205.
