CEWELD 2594 Super Duplex

Product category
Type
2594 Super Duplex stainles steel Mig/Mag GMAW welding wire for Zeron 100, Uranus 76, SAF 2507 and similar alloys
Applications
Welding austenitic-ferritic, stainless alloys of the 25% Cr, 7% Ni, 4% Mo, low C types. Welding wrought, forged or cast super duplex stainless steels for service in the as-welded Condition. Heterogeneous welding between super duplex stainless steels and dissimilar welds between other stainless and mild or low alloyed steels. The alloy is widely used in applications in which corrosion resistance is of the utmost importance. The pulp & paper industry, offshore and gas industry are areas of interest.
Properties

CEWELD 2594 has high intergranular-corrosion, pitting and stress-corrosion resistance with exceptional mechanical strength properties.
