25% Cr Superduplex Zeron 100X Sub Arc wire. For applications where Zeron® 100X wire is to be used for welding super-martensitic stainless steels, it is possible for the wire to be supplied with a total hydrogen content of 3ppm maximum.
Applications
Zeron® 100 has an exceptional combination of strength and resistance to corrosion and erosion in a wide range of aggressive media. The presence of Cu+W provides superior resistance to sulphuric and hydrochloric acids when compared to similar alloys without these additions. Offshore applications exploit the high resistance to pitting and stress-corrosion cracking in seawater. It is also highly resistant to caustic alkalis and phosphoric acid. Service temperature range is usually limited to –50°C to 280°C, the upper limit owing to thermal instability ("450°C" and sigma embrittlement). It is widely used in oil and gas production and process pipework, risers, manifolds, pressure vessels, valves, pumps, desalination plants, systems for flue-gas desulphurisation (FGD) and also in the mining, chemical and pharmaceutical industries. Zeron® 100 wires are also used for joining super-martensitic stainless steels.
