This alloy has the following characteristics:
ERNiCr-3 (82 wire) The weld metal formed by wire welding has higher strength and better corrosion resistance, better oxidation resistance and higher creep rupture strength at high temperatures.
Metallographic structure of ERNiCr-3:
Face-centered cubic lattice structure.
ERNiCr-3 applications are:
ERNiCr-3 has a wide range of applications:
1. Welding wire ERNiCr-3 is used to weld INCONEL 600 \ 601 \ 690 alloy, INCOLOY 800 \ 800HT \ 330 alloy, and other methods, such as melting electrode gas shielded welding, tungsten inert gas shielded welding and submerged arc welding. weld. For submerged arc welding with NI-ROD 99 wire, use INCOFLUX 4 submerged arc flux. When submerged arc welding with INCOFLUX 6 submerged arc flux, the number of bead layers is up to three
2. It can be used for welding of dissimilar materials, such as welding of INCONEL series alloy, INCOLOY series alloy, or welding of INCOLOY 330 alloy with nickel, MONEL series alloy and stainless steel, and carbon steel. Carbon steel
