Hakan Nickel Alloys, based in Istanbul, Turkey, is a trusted manufacturer and global supplier of high-strength, corrosion-resistant components, including Duplex Steel Forgings. These forgings are crafted to endure extreme mechanical loads and harsh environments, ensuring remarkable durability and dimensional stability. Produced in line with international standards and customized to meet specific industrial requirements, Hakan Nickel Alloys offers Duplex Steel Forgings in various shapes like rings, blocks, shafts, and flanges. The company caters to industries such as oil and gas, marine, chemical processing, and heavy engineering.
Typically, Duplex Steel Forgings are made from grades like UNS S31803 (2205) and S32750 (2507), which feature a blend of austenitic and ferritic microstructures. The alloy composition—usually around 22–25% chromium, 4–7% nickel, and 3% molybdenum—delivers outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These forgings boast superior mechanical strength, nearly double that of standard austenitic stainless steels, along with excellent fatigue resistance, toughness, and thermal stability. They retain their strength and corrosion resistance even in high-pressure and high-temperature conditions.
