Kanish Metals is a reliable manufacturer and supplier of **Duplex Steel Bars and Rods** located in **Dubai, UAE**. We pride ourselves on providing top-notch stainless steel solutions that are built to withstand the toughest industrial challenges. Our duplex steel products are celebrated for their remarkable strength, resistance to corrosion, and durability even in the harshest environments. With a commitment to precision manufacturing and strict adherence to international standards, Kanish Metals caters to a diverse array of industries, including oil & gas, chemical processing, marine, and construction. We’re dedicated to delivering high-performance materials that promise a long service life and dependable performance in critical applications.
**Duplex Steel Bars and Rods** typically consist of **22–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum**, and **0.14–0.20% nitrogen**, which together create a dual-phase microstructure of austenite and ferrite. This unique structure provides **high tensile strength (620–880 MPa)**, **yield strength (≥450 MPa)**, and an **elongation of about 25%**. The alloy is known for its exceptional resistance to **pitting, crevice corrosion, and chloride stress corrosion cracking**. Its mechanical properties remain robust under high stress and in corrosive conditions, making it perfect for environments where both strength and corrosion resistance are vital.
