Duplex Steel Filler Wire

Duplex Steel Filler Wire is used for welding matching or similar alloys found in ASTM A182, A276, A329, UNS S31803 (F51), S32205 (F60), also found when welding dissimilar base metals such as Super duplex steels and stainless steels. Duplex Steel Filler Wire has very good resistance to general corrosion, the weld metal has a high resistance to pitting combined with good resistance to crevice corrosion as well as stress corrosion cracking. The nickel over matches the parent material by 2-3% to provide an optimum balance of austenite and ferrite in the as-welded condition.

 

Duplex Stainless Steel Filler Wire has generally a very good corrosion resistance that increases with the contents of Cr, Mo and N. Duplex Steel Welding Wire exhibit general corrosion, pitting and crevice corrosion, high resistance to stress corrosion cracking due to high strength, and high resistance to intercrystalline corrosion.

 

Duplex Stainless Steel Filler Wire are used for pipework and general fabrication in offshore oil applications, paper industry, oil industry, artificial manure production, gas and chemical process industries.
