CEWELD 2594 Tig (Super Duplex)

Product category
Type
Tig filler metal for welding Super Duplex types of stainless steels.
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

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