TYPICAL APPLICATIONS

• Standard duplex stainless steels UNS S31803 (wrought) J92205 (cast), ASTM F51, DIN 1.4462, BS 1501 318S13.
• Proprietary alloys such as Hy-Resist 22/5 (Avesta Sheffield), SAF 2205 (Sandvik), AF22 (Mannesmann), Uranus 45N (Creusot).
• The wire is designed for MIG welding standard duplex stainless steels meeting the requirements of UNS S31803. It over-matches the parent material by 2-3% with respect to Ni to give the correct micro- structural balance of austenite & ferrite in the as-welded condition. Used for pipe-work & general fabrication in the off-shore oil & gas & chemical process industries.

Duplex weld metal microstructure with austenite + 30-50% ferrite. Pitting resistance equivalent PRE = %Cr + 3.3 % Mo + 16% Ni is > 35
