They cater to both local and international clients, always prioritizing quality and precision. Their commitment to durability and adherence to global quality standards means that every product is designed to perform exceptionally well, even in the toughest conditions. Super Duplex Steel Bright Bars are celebrated for their remarkable strength, resistance to corrosion, and toughness, making them ideal for critical industries. Anucha Metals proudly supports sectors such as oil and gas, marine, petrochemical, and construction with dependable and long-lasting solutions.
Super Duplex Steel Bright Bars are high-performance alloy materials that encapsulate the properties of the most commonly known austenitic and ferritic stainless steels. Containing 22-25% chromium (Cr), 4-7% nickel (Ni), 3-5% molybdenum (Mo), and approximately 0.2% nitrogen (N), the product provides excellent corrosion resistance in chloride-rich environments. The alloy provides strength generally at between 550-800 MPa with good toughness against stress corrosion cracking. The microstructure essentially comprises about 50% austenite and about 50% ferrite, which produces superior mechanical properties, including tensile strength, resistance to pitting, crevice corrosion, and high-temperature stability, that make it an excellent candidate for demanding applications.

The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
These bars find extensive use in industries that require exceptional strength, corrosion resistance, and precise dimensions. In the oil and gas sector, they are essential for offshore platforms, pipelines, valves, and subsea equipment. The marine industry relies on them for propeller shafts, pumps, and seawater cooling systems. Chemical and petrochemical industries utilize these bars in reactors, heat exchangers, and pressure vessels. They also play a crucial role in desalination plants, construction projects, and the pulp and paper industry. Thanks to their superior machinability, toughness, and performance under extreme conditions, Super Duplex Steel Bright Bars are the go-to choice for critical industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
