Ni Cr Mo Alloy Welding Wire Mixed ERNiCrMo-3 Gas Protection Corrosion Resistant
Ni Cr Mo Alloy Mixed Gas Protection Corrosion Resistant Welding Wire ERNiCrMo-3
Nickel Based Welding Wire
ERNiCrMo-3, a Nickel-Chromium-Molybdenum alloy with low Carbon and Niobium addition, has superior resistance to high temperature effects such as oxidation and carburization as well as to a wide range of corrosive environments of unusual severity, especially resistance to pitting and crevice corrosion. Typical applications for inconel 625 are seawater applications, aerospace components, chemical processing equipment, nuclear water reaction components.
Alloy 625 Grade 2 is recommended for components that require optimum resistance to creep or rupture. Fine-grained (annealed) material may be advantageous at temperatures up to 1500°F with respect to fatigue strength, hardness, and tensile and yield strength.
Welding of Inconel 625
Any traditional welding procedures can be used to weld Inconel 625 to similar alloys or other metals, such as gas tungsten arc welding(GTAW), plasma arc welding (PAW), metal inertia gas welding (MIG) and so on. Before welding, remove scale, grease, mark and imprint. And no heat treatment needed before and after welding. Recommend filler wire regarding welding Inconel 625: ERNiCrMo-3
