Nickel electrode resists crevice corrosion, pitting

March 5, 2010

Select-Arc Inc. has introduced a gas-shielded, flux-cored, nickel-based electrode designed to resist crevice corrosion and pitting.

SelectAlloy C276-AP has been developed to weld nickel-chromium-molybdenum to itself or to other nickel-based alloys. Composed of 16 percent molybdenum, 15.5 percent chromium, 5.5 percent iron, and 4 percent tungsten, with a balance of nickel and low carbon, the electrode also is used for surfacing steel and for joining nickel-based alloys to steel.

The electrode performs in all positions. Typical applications include pipelines, pressure vessels, chemical processing plants, offshore oil and gas facilities, and marine environments.

The electrode is available in 0.045- and 0.0625-in. diameters.
