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.

Application
ERNiCrMo-3 (NA625) is used primarily for gas tungsten and gas metal
arc and matching composition base metals. It is also used for
welding Inconel 601 and Incoloy 800. It can be used to weld
dissimilar metal combinations such as steel, stainless steel,
Inconel and Incoloy alloys.
