Aws 5.14 ERNiCrMo-3
EN ISO 18274: S Ni6625 (NiCr22Mo9Nb)
DIN 1736: SG-NiCr21Mo9Nb (2.4831)
| FEATURES & APPLICATIONS |
6025 is used for gas tungsten arc welding of Inconel® alloy 625, Incoloy® alloy 825, Incoloy® alloy 25-6Mo and a range of high alloy austenitic and super austenitic stainless steels. It is also used for surfacing of steel, for welding 9% nickel steels, and for welding various corrosion resistant alloys such as alloy 20. The weld metal has high strength over a broad temperature range and has resistance to localized attack such as pitting and crevice corrosion.
