Würth 4462 MAG welding wire is made from austenitic-ferritic stainless duplex steel, ensuring high tensile strength and resistance to pitting and stress corrosion cracking. This wire is specially designed for welding, joining and cladding stainless steels of similar composition, and it is magnetisable and polishable. Pitting resistance index PRE = 35 ensures reliable performance in various welding applications. Suitable for petrochemical, offshore and sour gas industry applications, offering higher corrosion resistance than austenitic steels
- Austenitic-ferritic duplex stainless steel solid wire made of 22Cr9Ni3Mo steel alloy
- High tensile strength and resistance to pitting corrosion and stress corrosion
- Suitable for welding, joining and cladding (duplex) stainless steels of similar composition
- Can be magnetised and polished
- Pitting corrosion resistance index PRE = 35
- Applications include petrochemical and offshore industries (e.g. sheets and piping), where higher corrosion resistance is required than that provided by austenitic stainless steels in chloride environments and at temperatures of 50°C to 300°C
- Also suitable for use in the sour gas industry, chemical transport and the pulp and paper industry
