C276

 
C276 is a nickel molybdenum chromium tungsten alloy with the addition of Tungsten. C276 has good fabricability and impressive corrosion resistance in some of the most severe environments. Due to C 276's properties it is commonly used in pollution control, chemical, petrochemical and waste incineration applications.
C-276 is one of the most universally corrosion resistant alloys available today. It is used in a variety of environments ranging from moderately oxidizing to strong reducing conditions. C-276 has exceptional resistance to sulfuric acid, hydrochloric acid, formic acid, acetic acid, chlorides, solvents, wet chloride gas, hypochlorite and chlorine solutions. C-276 has excellent resistance to phosphoric acid at all temperatures below boiling and concentrations lower than 65%. The limiting factor when dealing with strong oxidizing environments is the low chromium content, which means hot concentrated nitric acid environments are not desirable.
 
C-276 has superior resistance to pitting, stress corrosion cracking and oxidizing atmospheres. Alloy C-276 also exhibits resistance to corrosion by seawater in crevice conditions, which can induce aggressive attack in other commonly used materials.
