Kanish Metals stands out as a top manufacturer and supplier in Dubai, UAE, specializing in high-quality Super Duplex Steel Hollow Bars tailored for industries that operate in tough, corrosive environments. These hollow bars are celebrated for their remarkable mechanical strength, outstanding durability, and exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Thanks to their unique dual-phase microstructure of ferrite and austenite, Super Duplex Steel Hollow Bars offer a perfect blend of toughness and strength, making them the go-to choice for critical applications in marine, oil and gas, petrochemical, and chemical processing sectors.
These hollow bars are primarily made up of 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which gives them incredible resistance to harsh environments. Their distinctive dual-phase structure guarantees high tensile strength, superior yield strength, and excellent fatigue resistance. Even under high pressures and elevated temperatures, these hollow bars maintain their toughness and stability. With their impressive resistance to chloride-induced stress corrosion cracking and general corrosion, they promise a long service life, ensuring reliable performance in challenging operating conditions and industrial applications.

Yes, Super Duplex Steel Hollow Bars can withstand high temperatures due to their excellent strength and corrosion resistance. They are suitable for applications in environments up to around 300°C (572°F), depending on the specific alloy.
Super Duplex Steel Hollow Bars and Rods are manufactured through hot or cold working processes, including extrusion and forging, followed by heat treatment, cold drawing, and precision machining for enhanced strength and corrosion resistance.
Super Duplex Steel Hollow Bars have excellent natural corrosion resistance due to their high chromium and molybdenum content, making additional protective coatings generally unnecessary. However, in highly aggressive environments, coatings may offer extra protection.
Super Duplex Steel Hollow Bars find their place in various industries that demand exceptional mechanical strength and corrosion resistance. They are widely used in offshore platforms, seawater desalination plants, chemical processing equipment, and marine engineering structures. In the oil and gas industry, you’ll find them in pipelines, subsea equipment, valves, and pressure vessels. Their robust characteristics also make them ideal for the pulp and paper industry, structural frameworks, and heat exchangers. With their ability to thrive in aggressive conditions, Super Duplex Steel Hollow Bars are a trusted choice for heavy-duty engineering and industrial projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
