Alloy C276 tubing / Hastelloy C276 tubing Advantages
C276 tubing has excellent corrosion resistance in a broad range of extreme environments. Due to the high molybdenum content, C276 alloy especially has good performance on resistance to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
