Kanish Metals stands out as a reliable manufacturer and supplier based in Dubai, UAE, specializing in top-notch Super Duplex Steel Hex Bars. These bars are crafted to offer exceptional strength and withstand the toughest industrial conditions. Known for their impressive corrosion resistance, durability, and high mechanical strength, they’re perfect for demanding sectors like marine, chemical, oil, and gas. Thanks to their unique dual-phase microstructure of ferrite and austenite, Super Duplex Steel Hex Bars provide remarkable toughness and resist pitting and crevice corrosion, ensuring they perform reliably in critical engineering tasks.
These hex bars are made up of 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which greatly enhance their corrosion resistance and mechanical stability. Their dual-phase design results in high tensile strength, excellent yield strength, and outstanding fatigue resistance. Even in high temperatures and under pressure, these bars maintain their toughness. Their exceptional resistance to chloride stress corrosion cracking and harsh environments guarantees long-lasting durability, making them suitable for a variety of industrial and structural uses.

Yes, Super Duplex Steel Hex Bars are magnetic due to their mixed microstructure of austenite and ferrite, which gives them magnetic properties, though they are less magnetic than ferritic steels.
Yes, Super Duplex Steel Hex Bars are suitable for hygienic and sanitary applications due to their corrosion resistance, durability, and ease of cleaning, making them ideal for industries like food processing and pharmaceuticals.
Super Duplex Steel Hex Bars are less susceptible to galvanic corrosion compared to other materials due to their high corrosion resistance. However, they may still experience galvanic corrosion when in contact with less resistant metals.
Super Duplex Steel Hex Bars find extensive application in industries that demand both superior corrosion resistance and high mechanical strength. They are commonly used in offshore platforms, marine engineering, desalination plants, and chemical processing equipment. In the oil and gas industry, you’ll find them in pipelines, valves, fasteners, and subsea components. Their robust characteristics make them perfect for pressure vessels, heat exchangers, and structural frameworks in corrosive settings. With their ability to endure tough conditions, Super Duplex Steel Hex Bars are a dependable choice for heavy-duty industrial and engineering projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
