Al Shakru Sheets and Plates, a leading manufacturer and supplier based in Dubai, UAE, focuses on high-performance Super Duplex Steel Coils and Slitting Coils engineered for outstanding strength, corrosion resistance, and durability. These coils are designed to satisfy the demanding requirements of sectors such as oil and gas, petrochemical, marine, and chemical processing. Celebrated for their remarkable resistance to pitting, crevice corrosion, and stress cracking, Super Duplex Steel Coils provide reliable performance even in the harshest conditions. Al Shakru Sheets and Plates takes pride in precision manufacturing, guaranteeing high dimensional accuracy and adherence to international standards, which makes their products ideal for critical and long-lasting industrial applications.
Super Duplex Steel Coils and Slitting Coils are composed of roughly 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, with iron accounting for the remainder. Their distinctive two-phase microstructure of austenite and ferrite gives them exceptional mechanical strength and resistance to corrosion. They generally exhibit a tensile strength of about 800 MPa, a yield strength of 550 MPa, and outstanding impact toughness. The material strongly resists chloride-induced stress corrosion cracking, features excellent weldability, and delivers enduring durability in high-pressure and high-temperature environments.
