It is one of the unique materials characterized by high strength, corrosion resistance, and weldability. Applications are found across various industries, including construction, marine engineering, and the oil and gas sector. Duplex Steel Hex Bar with its hexagonal profile is ideal for bolted connections and applications. High torsional strength is required. We are committed to supplying a wide range of sizes and grades of this material. Assuring customers receive the precise solutions needed for their specific projects backed by expert knowledge and reliable service.
Duplex steel hex bars are a unique type of metal product characterized by their dual-phase microstructure. Comprising roughly equal parts of austenite and ferrite. This combination gives them superior strength and corrosion resistance compared to standard austenitic or ferritic stainless steels. Typically duplex alloys include around 22-25% chromium, 5-7% nickel, 3-3.5% molybdenum. and a small amount of nitrogen. The hexagonal shape allows for easy gripping and torque application. Making these bars ideal for applications requiring high mechanical strength, such as fasteners, shafts and structural components in harsh environments like the oil and gas, chemical and marine industries.
