Renowned for our precision, quality, and dependability, we provide stainless steel products that not only meet global standards but also cater to our clients’ specific needs. Our Super Duplex Steel Rectangular Bars are highly valued for their exceptional strength, resistance to corrosion, and durability, even in the toughest environments. By employing cutting-edge manufacturing techniques and rigorous quality control, Starc Metals supports vital industries such as oil and gas, marine, chemical processing, and power generation, offering high-performance solutions that guarantee long-lasting reliability, safety, and efficiency in critical industrial applications.
These Super Duplex Steel Rectangular Bars are primarily made up of 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which together create a duplex microstructure of austenite and ferrite. This unique composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive settings. Their mechanical properties boast a tensile strength ranging from 800 to 950 MPa, a yield strength of about 550 MPa, and a density of 7.8 g/cm³. Additionally, these bars offer high impact toughness, good weldability, and stability under extreme temperatures and pressures, making them perfect for critical industrial applications that require both strength and corrosion resistance.

When selecting Super Duplex Steel Rectangular Bars, consider factors like corrosion resistance, mechanical strength, operating temperature, application environment, and compliance with industry standards for optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be welded using appropriate techniques such as TIG or MIG welding. However, proper heat control is necessary to maintain their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not ideal for cryogenic applications, as their toughness and ductility may decrease at extremely low temperatures, potentially leading to brittleness in such environments.
Super Duplex Steel Rectangular Bars find extensive use in industries that demand high mechanical strength and excellent corrosion resistance. In the oil and gas sector, they are utilized in pipelines, pressure vessels, and subsea equipment. The marine industry employs them in shipbuilding, offshore platforms, and desalination plants, thanks to their resistance to seawater. Chemical and petrochemical sectors use these bars for reactors, heat exchangers, and storage tanks. They are also applied in power generation, pulp and paper production, and heavy industrial machinery. At Starc Metals, we ensure precise manufacturing to deliver durable and high-performance Super Duplex Steel Rectangular Bars that meet the highest standards.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
