The extensively used 2205/ UNS S31803 grade duplex steel has a superior chemical makeup and high tensile strength. This nickel, molybdenum, and chromium alloy exhibits outstanding resistance to pitting and crevice corrosion. This alloy has a 25% chromium content, a 4% molybdenum content, and a 7% nickel content. We design excellent quality and high-performance flanges using a pure grade alloy that offers extraordinary resistance to general corrosion and chloride pitting corrosion attack in harsh situations. For the creation of Duplex 2205/ UNS S31803 Flanges, the highest quality raw materials are obtained from a well-known source on the international market. Before usage, the raw material is checked correctly to ensure that no flanges of subpar quality are created.
Applications of Duplex 2205/31803 Flanges:
- » Duplex 2205/31803 Flanges are suited for architectural applications in harsh situations, from polluted maritime environments to places with sub-zero temperatures, thanks to molybdenum and slightly more excellent nickel content.
- » Duplex steel 2205 flanges are widely used in different industries like producing electricity, textiles, petrochemicals, pharmaceuticals, heat exchangers, gas processing, sea water equipment, chemical equipment, mining, oil drilling companies, specialty chemicals, condensers, pulp and paper, and many more.
