EN10216-5 UNS S31803 Duplex Stainless Steel Seamless Tube
EN10216-5 UNS S31803 is a specification for duplex stainless steel seamless tubes. Duplex stainless steel is a type of stainless steel that contains a balanced proportion of ferrite and austenite phases, which gives it excellent corrosion resistance and high strength.
The EN10216-5 standard specifies the technical delivery conditions for seamless tubes made from stainless steels for pressure purposes. UNS S31803 is a grade of duplex stainless steel that has a composition of 22% chromium, 5% nickel, 3% molybdenum, and 0.15% nitrogen.
Duplex stainless steel seamless tubes are commonly used in industries such as oil and gas, chemical processing, and marine applications, where corrosion resistance and high strength are required. They are also suitable for use in environments with high temperatures and pressures.
The seamless manufacturing process ensures that the tubes have a smooth and uniform surface, which enhances their corrosion resistance and makes them suitable for use in critical applications. Additionally, the seamless design eliminates the risk of leakage and ensures the integrity of the tubes.
Overall, EN10216-5 UNS S31803 duplex stainless steel seamless tubes are a reliable and durable choice for various industrial applications that require excellent corrosion resistance and high strength.
