These coils are celebrated for their remarkable strength, resistance to corrosion, and durability, making them perfect for tough industrial settings. Crafted with cutting-edge metallurgical techniques and precise rolling methods, these coils guarantee a consistent thickness, excellent surface finish, and reliable mechanical properties. Tanvir Nickel Alloys supplies Super Duplex Steel Coils for essential uses in the oil and gas, chemical processing, petrochemical, and marine sectors. Their impressive mechanical strength, along with their ability to resist pitting and stress corrosion cracking, ensures they perform well in demanding and high-performance environments.
Super Duplex Steel Coils typically contain around 22–25% chromium, 4–6% nickel, and 3–5% molybdenum, with nitrogen and iron forming the base. They boast a tensile strength between 800 and 1000 MPa, a yield strength of about 550–700 MPa, and an elongation of 25–30%. This alloy is known for its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, as well as its high toughness and durability. These characteristics make Super Duplex Steel Coils ideal for applications that involve high pressure, high temperatures, and aggressive chemicals.
