Hakan Nickel Alloys, based in Istanbul, Turkey, is a trusted name when it comes to manufacturing and supplying corrosion-resistant alloy fasteners, including Hastelloy Nuts. These nuts are designed to excel in tough environments where chemical exposure, high pressure, and extreme temperatures are everyday challenges. Adhering to international standards, Hakan Nickel Alloys offers Hastelloy Nuts in a range of sizes, threads, and specifications to meet various industrial needs. The company caters to essential sectors like chemical processing, marine engineering, power generation, and aerospace, providing fastening solutions that prioritize safety, durability, and structural integrity even in the harshest conditions.
Hastelloy Nuts are crafted from nickel-based alloys such as Hastelloy C-276, C-22, and C-2000. These materials blend nickel, molybdenum, chromium, and iron, delivering outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in both oxidizing and reducing environments. On the mechanical side, Hastelloy Nuts boast high tensile strength, good ductility, and the ability to perform well undser thermal cycling and heavy mechanical loads. They maintain their strength and corrosion resistance even in highly acidic, chloride-rich, and high-temperature settings.
