Alloy C276 nickel pipe is made from a nickel-molybdenum-chromium alloy with addition of tungsten having excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes this 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.

Applications of EN 2.4819 / Alloy C276 Pipe

Some typical applications include equipment components in chemical and petrochemical organic chloride processes and processes utilizing halide or acid catalysts. Other industry applications are pulp and paper (digesters and bleach areas), scrubbers and ducting for flue gas desulfurization, pharmaceutical, and food processing equipment.

Alloy C-276 sheet 0.044" thick in the heat-treated condition at 2050 °F, rapid quenched, has an average olsen cup depth of 0.48". C-276 can be successfully fabricated by many methods. The alloy tends to work harden but with the proper care, the alloy is readily hot and cold formed.
