The **Incoloy 825 Coils** from Okoye Nickel Alloys are crafted from a blend of nickel, iron, and chromium, with notable additions of molybdenum, copper, and titanium. This distinctive composition grants them exceptional resistance to sulfuric and phosphoric acids, as well as to both oxidizing and reducing agents, and protects against chloride-induced stress corrosion cracking. The alloy boasts a tensile strength of around 550 MPa, a yield strength of about 220 MPa, and an elongation of roughly 30%. Incoloy 825 also retains its mechanical properties even at elevated temperatures, ensuring outstanding performance and durability in both chemical and thermal settings.
The **Incoloy 825 Coils** produced by Okoye Nickel Alloys find extensive applications in chemical processing equipment, heat exchangers, evaporators, marine exhaust systems, pickling tank heaters, and pollution-control devices. Their high corrosion resistance makes them particularly well-suited for environments rich in acids and chlorides. Additionally, these coils are utilized in oil and gas recovery systems, power plants, and offshore industries where strength and stability are paramount. Okoye Nickel Alloys is dedicated to precise manufacturing, ensuring dimensional accuracy and rigorous testing to deliver Incoloy 825 Coils that promise a long service life, exceptional reliability, and superior performance even under the most demanding industrial conditions.
