Alloy C276
UNS N10276
Werkstoff – Nr. 2.4819
AWS A5.14
Alloy C276 (ERNiCrMo-4) have an excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes the alloy especially resistant to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
