These alloys offer properties including high strength and toughness, excellent performance at high temperature, excellent corrosion resistance in seawater and good resistance in hydrofluoric acid, dilute non-oxidising acid, alkalis and salts. As such, nickel alloys are widely used and specified for components in the offshore oil and gas, chemical processing and nuclear industry.
The nickel chromium alloys, i.e. Alloy 600 and Alloy 825, offer various levels of high temperature strength, pitting resistance, corrosion and erosion resistance in a wide range of organic and mineral acids as well as sulphides and chlorides. Hastelloy C276 has a high molybdenum content giving it a remarkable pitting and crevice corrosion resistance in a wide range of processing environments.
