Hakan Nickel Alloys in Istanbul, Turkey makes Hastelloy Fasteners, which are strong metal items like bolts, screws, and nuts used to hold parts together tightly. These fasteners are very tough and can handle high heat, pressure, and harsh chemicals without rusting or breaking. Hastelloy Fasteners are used in chemical plants, power plants, oil and gas industries, ships, and aerospace. Hakan Nickel Alloys ensures every fastener is smooth, strong, and reliable. Engineers and workers can use them safely for a long time, providing secure and long-lasting connections in equipment that must withstand tough industrial conditions.
Hastelloy Fasteners are made mainly of nickel, molybdenum, and iron, with small amounts of chromium and cobalt. This makes them very strong, corrosion-resistant, and heat-resistant. They can handle high temperatures and heavy pressure without bending, cracking, or rusting. The fasteners remain durable even after long-term use in harsh industrial environments. These properties make Hastelloy Fasteners perfect for connecting machinery, pipes, and equipment in chemical plants, power plants, oil and gas industries, ships, and aerospace where ordinary steel fasteners would fail.
