What is alloy C276?
lloy C-276 / UNS N10276 / W.Nr. 2.4819
describe
Alloy C-276 is a solid solution strengthened nickel-molybdenum-chromium alloy containing a small amount of tungsten. Alloy C-276 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 environments where corrosive chemical environments exist and where other alloys would fail.
Industries and Applications
Alloy C-276 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-use applications include chimney liners, ducts, dampers, scrubbers, flue gas reheaters, heat exchangers, reaction vessels, evaporators, transfer piping and many other highly corrosive applications.
preservative
Alloy C-276 is one of the most common corrosion-resistant alloys available today. It can be used in a variety of environments from moderately oxidizing conditions to strongly reducing conditions. Alloy C-276 has excellent resistance to sulfuric acid, hydrochloric acid, formic acid, acetic acid, chlorides, solvents, wet chloride gases, hypochlorites and chlorine solutions. Alloy C-276 has excellent resistance to phosphoric acid at all temperatures below the boiling point and at concentrations below 65%. The limiting factor when dealing with strongly oxidizing environments is the low chromium content, which means hot concentrated nitric acid environments are undesirable.
Alloy C-276 has excellent resistance to pitting corrosion, stress corrosion cracking and oxidizing atmospheres. Alloy C-276 also provides resistance to seawater corrosion in crevice conditions that can cause erosion of other commonly used materials.
