George Metals, based in Houston, USA, is a reliable manufacturer and supplier of top-notch Hastelloy C22 Forgings, crafted for outstanding performance in highly corrosive settings. Hastelloy C22 is a flexible nickel-chromium-molybdenum-tungsten alloy that provides remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking in both oxidizing and reducing environments. At George Metals, we create a diverse array of forged components, including rings, discs, flanges, shafts, and custom shapes, all in line with standards like ASTM B564. Our forgings find their place in industries such as chemical processing, marine, pharmaceuticals, pollution control, and nuclear waste management, where long-lasting reliability is crucial.
Hastelloy C22 Forgings from George Metals are composed of nickel (balance), 20–22.5% chromium, 12.5–14.5% molybdenum, 2.5–3.5% tungsten, along with trace amounts of iron, cobalt, and vanadium. This unique blend ensures exceptional corrosion resistance across a variety of harsh environments, including those with chlorides, oxidizing acids, and mixed chemical solutions. These forgings boast a tensile strength of around 690 MPa, a yield strength of about 283 MPa, and impressive ductility. Typically, they are provided in a solution-annealed state, guaranteeing optimal mechanical integrity, weldability, and resistance to intergranular corrosion in demanding industrial applications.
