Alloy C276 pipe fittings are generally considered to be a universal anti-corrosion alloy. They are suitable for corrosive environments such as inorganic acids, organic/inorganic chlorine-contaminated media, formic acid, acetic acid, acetic anhydride, sea water, and salt water solutions. They can withstand pit corrosion, crevice corrosion, and stress. Corrosion cracking.
