Hakan Nickel Alloys, located in Istanbul, Turkey, has built a solid reputation as a reliable manufacturer and supplier of corrosion-resistant alloy components, including Incoloy 825 Flanges. These flanges are designed to perform exceptionally well in harsh chemical and high-temperature settings, providing outstanding resistance to acids, chloride stress corrosion, and oxidation. Thanks to their advanced production capabilities and rigorous quality standards, Hakan Nickel Alloys ensures that their Incoloy 825 Flanges comply with international standards and meet specific industry needs. They cater to various sectors, such as chemical processing, oil and gas, marine, and pollution control, and are recognized for their dependability, precision manufacturing, and unwavering customer support across global markets.
Incoloy 825 Flanges are made up of nickel (38–46%), iron (up to 39%), chromium (19.5–23.5%), molybdenum (2.5–3.5%), and copper (1.5–3.0%), with titanium and aluminum serving as stabilizing elements. This well-balanced composition grants them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in both oxidizing and reducing environments. On the mechanical side, the alloy boasts a tensile strength of about 585 MPa and a yield strength of around 240 MPa, along with good ductility and toughness. Incoloy 825 Flanges maintain their structural integrity even under thermal cycling and mechanical stress in corrosive service conditions.
