Hakan Nickel Alloys, Istanbul, Turkey, is a trusted supplier and manufacturer of top-quality Inconel fasteners. Famed for their accuracy and strength, the company manufactures fasteners of international quality that are designed to withstand harsh conditions. Inconel fasteners have superior resistance to corrosion, oxidation, and high temperatures, making them ideal for critical industrial applications. With a high emphasis on quality and customer satisfaction, Hakan Nickel Alloys delivers fastening products of the highest reliability for a wide range of industries that demand strength and long-term performance under extreme conditions.
Inconel fasteners are manufactured from nickel-chromium superalloys, including Inconel 600, 625, 718, etc., each of which is designed for specific applications. These alloys have a high tensile strength, superior fatigue resistance, and superior resistance to corrosion in hostile environments, such as in acids, oxidizing environments, and chloride-rich media. Inconel fasteners retain mechanical strength within a broad temperature range, from cryogenic temperatures to temperatures over 1000°C. Due to their superior weldability and resistance to thermal fatigue and stress corrosion cracking, they are well suited to critical and high-stress applications.
