George Metals, based in Houston, USA, stands out as a top manufacturer and supplier of high-quality Incoloy 825 Forgings, celebrated for their exceptional corrosion resistance and strength in harsh chemical and marine settings. Incoloy 825 is a nickel-iron-chromium alloy enriched with molybdenum, copper, and titanium, which provides remarkable resistance to acid attacks, stress corrosion cracking, and oxidation. George Metals offers a diverse array of forged components, including shafts, discs, rings, flanges, and custom shapes, all adhering to ASTM B564 and various international standards. These forgings find extensive use in chemical processing, offshore oil and gas, pollution control, and nuclear fuel reprocessing.
Incoloy 825 Forgings from George Metals consist of 38–46% nickel, 19.5–23.5% iron, 19.5–23.5% chromium, 2.5–3.5% molybdenum, 1.5–3% copper, and 0.6–1.2% titanium. This well-balanced composition ensures excellent resistance to sulfuric, phosphoric, and nitric acids, along with protection against chloride-induced stress corrosion cracking. When annealed, it boasts a tensile strength of around 585 MPa, a yield strength of about 220 MPa, and impressive ductility. George Metals guarantees that each forging undergoes solution annealing, ultrasonic testing, and chemical verification, ensuring consistent mechanical performance even in highly corrosive and high-temperature environments.
