Hastelloy C276 is a solid solution strengthened nickel-molybdenum-chromium alloy containing a small amount of tungsten. Hastelloy C276 exhibits excellent corrosion resistance in various harsh environments and media. Like many other nickel alloys, it is ductile and easy to shape and weld. This alloy is used in most industrial applications where aggressive chemical environments exist where other alloys have failed.
Industries and Applications:
Hastelloy C276 is frequently used in many industries, including chemical and petrochemical processing, oil and gas, power generation, pharmaceuticals, pulp and paper production, and wastewater treatment. End applications include chimney liners, piping, valves, scrubbers, stack gas reheaters, heat exchangers, reaction vessels, evaporators, transfer piping and many other highly corrosive applications.
Corrosion resistance:
Hastelloy C276 is one of the most commonly used corrosion-resistant alloys today. It is used in a variety of environments from moderately oxidizing to strongly reducing conditions. Hastelloy C276 exhibits excellent corrosion resistance to sulfuric acid, hydrochloric acid, formic acid, acetic acid, chlorides, solvents, wet chlorine gas, hypochlorite and chlorine solutions. Hastelloy C276 provides excellent corrosion resistance at all boiling points and in phosphoric acid environments below 65% concentration. The limiting factor when dealing with strongly oxidizing environments is the low chromium content, which means it is not suitable for use in concentrated nitric acid environments.
Hastelloy C276 has superior resistance to pitting corrosion, stress corrosion cracking and oxidizing atmosphere corrosion. Hastelloy C276 also exhibits corrosion resistance to seawater in crevice conditions where other commonly used materials can trigger aggressive corrosion attacks.
Processing and heat treatment:
Hastelloy C276 can be formed using a variety of cold and hot working processes. Like other nickel alloys, Hastelloy C276 hardens quickly but can be cold formed using aggressive methods such as deep drawing, pressing and stamping. Thermoforming should be performed in a temperature range between 1600°F and 2250°F (870°C and 1230°C), with heavier parts should be heated to a minimum temperature of 2000°F before forming. It is recommended that the material be annealed after processing, which should be done between 2050°F and 2150°F, followed by rapid quenching in a protective atmosphere or stirred reduction quench bath. To obtain a reducing quench bath, add 2% (by volume) ethanol or propanol to the water.
