Bristow Nickel Alloys is a leading manufacturer and supplier in Midland, UK, high-performance nickel alloys and industrial-grade metal solutions. Focused on quality and innovation Bristow Nickel Alloys provides superior products that meet various industries. Among its vast range of offerings the company specializes in Duplex Steel Valves which are highly renowned for their enhanced strength, corrosion resistance and durability. These valves are best suited for demanding applications in chemical processing, oil and gas, and marine environments providing , reliability and best performance in harsh conditions.
Duplex Steel Valves consist of around 22-25% chromium, 5-7% nickel, 3-4% molybdenum, and small traces of nitrogen. The above composition provides high corrosion resistance and very good mechanical strength. They show a tensile strength of 620-850 MPa and yield strength of 450-550 MPa, with an elongation of about 25%. The density of the valves is 7.8 g/cm³, thermal conductivity of 19 W/mK, and melting range of 1350-1400°C. Their two-phase microstructure integrates ferritic and austenitic steels’ best properties suited for tough and challenging environments.
