Hakan Nickel Alloys of Istanbul, Turkey, is a trusted producer and supplier of high-quality nickel alloy parts, such as Inconel 625 fasteners. Specially designed to function in harsh environments, these fasteners are manufactured in accordance with global standards and possess higher mechanical strength and corrosion resistance. Hakan Nickel Alloys has a reputation for supplying accurate, precision-designed products that are relied upon in a broad spectrum of harsh industries. Their Inconel 625 fasteners are best suited for applications that demand long-term strength, superior chemical resistance to hostile chemicals, and stability at high pressure and temperature.
Inconel 625 fasteners consist of a nickel-chromium-molybdenum-niobium alloy that has superior resistance to a variety of corrosive conditions such as seawater, acidic chemicals, and oxidizing or reducing agents. These fasteners have high tensile strength (up to 827 MPa), superior fatigue and stress corrosion cracking resistance, and maintain their mechanical properties within a broad temperature range—from cryogenic temperatures up to 1000°C. The high molybdenum content in the alloy confers enhanced resistance to pitting and crevice corrosion, particularly in chloride-bearing environments.
