Nihonweld N-NiCrFe-2 description: Ni-CrFe-2 is a nickel-chromium-iron flux-coated electrode designed primarily for shielded metal arc welding of Incoloy 800 to itself or to 9% nickel steels. This electrode is used for welding a variety of dissimilar wrought or cast forms of carbon steel, austenitic and ferritic stainless steel, and nickel-chromium Inconel 600 to themselves or to each other. NIHONWELD N-NiCrFe-2 is frequently used for joining Incoloy 800 to high nickel alloys 200 and 201 or to nickel-copper Monel 400 and K-500.
