Alloy C276 is the alloy for outstanding performance in a range of aggressive environments. It is resistant to strong oxidizing chlorides, reducing acids, hot seawater and brine solutions. Alloy C276 is one of the few materials resistant to wet chlorine gas, hypochlorite and chlorine dioxide. Alloy C276 has excellent resistance to chloride pitting, crevice corrosion and stress corrosion cracking. Alloy C276 is oxidation resistant to 1800°F in open air. However, Alloy C276 is generally not recommended for elevated temperature service. The high molybdenum content renders Alloy C276 susceptible to catastrophic oxidation in stagnant conditions, such as under solid deposits.
