CLASSIFICATIONS: ENiCrMo4T1-1/4 per AWS A5.34

A gas-shielded, flux cored, nickel-based electrode, SelectAlloy C276-AP contains a nominal weld metal composition of 16% molybdenum, 15.5% chromium, 5.5% iron, 4% tungsten with a nickel balance and low carbon. This premium wire is primarily used for welding Ni-Cr-Mo to itself or to other nickel-based alloys as well as surfacing steel and for joining nickel-based alloys to steel.

APPLICATIONS: SelectAlloy C276-AP delivers excellent resistance to crevice corrosion and pitting. This electrode is utilized in pipelines, pressure vessels, chemical processing plants, offshore oil and gas facilities and marine environments.

DIAMETER: .045", 1/16"

SHIELDING GAS: 100%
CO2, 75% Ar/25% CO2, 30-40 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Outstanding performance characteristics in all positions.
  • Significantly higher deposition rates than those achieved with solid wires or covered electrodes.
