Nickel alloy C276 is a high-performance nickel-molybdenum-chromium superalloy with added tungsten, specifically engineered for outstanding corrosion resistance in extreme conditions. The combination of high molybdenum, chromium, and tungsten content enhances its resistance to pitting and crevice corrosion in reducing environments, while chromium contributes to its durability in oxidizing media. Additionally, the low carbon content helps prevent carbide precipitation during welding, ensuring superior corrosion resistance in as-welded structures.
One of the key advantages of alloy C276 tube is its exceptional resistance to grain boundary precipitates in the weld heat-affected zone, making nickel alloy C276 pipe highly suitable for demanding chemical process applications without requiring post-weld heat treatment. These properties make it a preferred material in industries dealing with highly corrosive conditions, including mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and sour oil and gas recovery.
