Austenitic ferritic duplex — solid wire made from stainless 22Cr9Ni3Mo steel alloy. The wire has high tensile strength and resistance to cracking caused by pitting corrosion and stress corrosion.
Suitable for welding, combining and coating stainless steels of a similar composition (duplex).
It can be magnetised and polished.
Pitting corrosion index PRE =35.

Applications: Petrochemical and offshore industry (e.g. sheets, piping), where much higher corrosion resistance is required than can be provided by austenitic stainless steel
in environments with high levels of chloride and in temperatures ranging from 50°C–300°C.
Applications: Acid gas industry, transportation of chemical products, applications aimed at reducing contamination, pulp and paper industry.
