Alloy C276, Hastelloy® C276 Nickel Alloy Pipe ASTM B622 ASME SB622 UNS N10276
C276 is an alloy of nickel,molybdenum,chrome with added tungsten; giving outstanding corrosion resistance in a range of severe environments’. Alloy C276 has excellent pitting and crevice corrosion resistance due to its high molybdenum content.
The carbon content is low which reduces carbide precipitation during welding so retains its corrosion resistance in as-welded fabrications.
Chemipetro supplies C276 in the following Product Forms:
Seamless pipe to ASTM B622 and ASME SB622
Welded pipe to ASTM B619 and ASME SB619
Flanges to ASTM B564 and ASME SB564
Fittings to ASTM B366 and ASME SB366
Bar to ASTM B574 and ASME SB574
Plate to ASTM B575 and ASME SB575
