Hakan Nickel Alloys, based in Istanbul, Turkey, stands out as a leading manufacturer and supplier of high-performance, corrosion-resistant components, including Hastelloy Washers. With a strong emphasis on quality, durability, and precision, the company produces washers designed to excel in the harshest chemical and high-temperature conditions. Crafted to meet international standards, their Hastelloy washers are relied upon by various industries, such as chemical processing, marine, aerospace, and power generation. Hakan Nickel Alloys is recognized for its dedication to excellence, prompt delivery, and technical support, making them a trusted partner for demanding industrial applications that require long-lasting performance.
Hastelloy Washers are crafted from nickel-based alloys, primarily featuring nickel (up to 70%), along with notable amounts of molybdenum, chromium, iron, and cobalt, depending on the specific grade (like C-22 or C-276). These elements grant them outstanding resistance to both oxidizing and reducing environments. The washers exhibit impressive tensile strength (690–785 MPa), yield strength (280–345 MPa), and elongation (up to 45%). They maintain their mechanical stability even under thermal stress and resist pitting, crevice corrosion, and stress corrosion cracking. Their strong physical and chemical properties make them perfect for high-pressure and corrosive applications that demand long-term sealing integrity.
