Hastelloy Alloy C-276 Pipes & Tubes

Material Description UNS N10276 Chemical Composition, % Ni Mo Cr Fe W Co Mn C V P S Si Bal. 15.0-17.0 14.5-16.5 4.0-7.0 3.0-4.5 2.5 max 1.0 max .01 max .35 max 0.04 max .03 max .08 max Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments. Characteristics ● One of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

● Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.

● Not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications

Application

● Digesters and bleach plants in the paper industry.

● Tubing exposed to sour gas.

● Tubing for flue-gas desulfurisation plants.

● Evaporator tubing, heat exchanger tubing, filters and mixers used in sulfuric acid environments.

● Tubing for sulfuric acid reactors.

● Tubing for organic chloride process equipment.

● Tubing for processes utilizing halide or acid catalysts.
