C276 is a nickel chromium molybdenum alloy, which is known for its excellent corrosion resistance in various corrosive media. It is a popular choice among a variety of applications including chemical and pharmaceutical processing, waste fluid treatment systems and power generation. It has also been used in a number of petrochemical, halide catalyst and flue gas desulfurization processes.
Hastelloy C276 is a highly corrosion resistant alloy that has outstanding properties in pitting corrosion. The alloy is especially suited for oxidizing and non-oxidizing acids, such as sulfuric acid. It is also resistant to chloride-induced stress corrosion cracking. The high concentration of molybdenum in the alloy makes it even more corrosion resistant.
Hastelloy C276 can be produced in a wide range of forms, such as forgings, stainless steel pipes, plates and wires. It is also highly suited for chemical and pollution control. The alloy can be deep drawn, forged, punched and spun. It is commonly used in cryogenic service, sour service environments and other aggressive environments. The alloy is also very good at reducing pressure during welding.
In addition to its excellent corrosion resistance, C276 has good resistance to crevice and stress corrosion cracking. Compared to other nickel-chromium-molybdenum alloys, Hastelloy C276 is also highly resistant to chlorite and hypochlorite solutions. It also has a high work hardening rate and excellent strength. It is normally solution heat treated at 2050 degF. It is then rapidly cooled to 1121 degC. It has a low carbon content, which minimizes carbide precipitation during welding.
