DESCRIPTION
ERNiCrMo-3 is nickel based type material designed for welding of nickel-chromium-molybdnenum alloys. Maybe used for cladding and welding of dissimilar base metals, like NiCrMo alloys to stainless steels, mild and low-alloyed steels. Characterized by high strength over a vide temperature range, extreme resistance to various corrosion forms, including resistance to pitting and crevice corrosion.
Recommended for overlaying of tubes and tube panels where low dilution of iron and high deposits of chromium are required.
