PRODUCT INFORMATION
What is UNS S31803 Duplex Steel Round Bar?
UNS S31803 round bars are made of the duplex stainless steel grade, which combines ferritic and austenitic microstructures, providing greater strength and resistance to corrosion when compared with standard stainless steels. S31803 bar is well-known for its exceptional toughness, superior mechanical strength, and superior resistance to crevice, pitting corrosion, and stress cracking. The duplex alloy is typically composed of approximately 22% chromium, 5-6% nickel, and 3% molybdenum. This makes it suitable for use in highly acidic environments, such as chemical and marine industries. S31803 round bar has excellent weldability and forming, and is ideal for both precision and structural engineering applications.
Applications and Benefits of UNS S31803 Duplex Steel Round Bar
UNS S31803 bar is used extensively in various industries, including oil and gas, chemical processing, energy generation, marine engineering, and desalination facilities. Its superior resistance to corrosion is ideal for pressure vessels, pipelines, heat exchangers, and structural parts that are exposed to harsh environments. Its primary advantages are its superior strength (nearly double the strength of austenitic stainless steels), high resistance to cracking due to chloride stress, and long service life with little maintenance. The choice of S31803 round bar will help you save money by reducing the thickness of the material and still maintaining strength, resulting in less weight but more robust equipment.
Uses of UNS S31803 Duplex Steel Round Bar
S31803 bar is typically used to manufacture shafts and valves, fasteners, fittings, and flanges used in process industries. It is also used in the manufacturing of bridge construction, marine components, digesters for pulp and paper, and pipes for heat exchangers. The strength of its fatigue and resistance to impact at high and sub-zero temperatures makes UNS S31803 round bars ideal for applications where reliability and durability are essential.
