At Metals and Welding Specialities, we supply top-grade ERNiCrMo-10 filler wires engineered for reliability in extreme conditions across industries like chemical processing, marine, and power generation.

What is ERNiCrMo-10 Filler Metal?

ERNiCrMo-10 is a nickel-chromium-molybdenum (Ni-Cr-Mo) alloy welding filler metal classified under AWS A5.14 standards. It is specifically developed for welding advanced alloys such as Hastelloy, Inconel, and other nickel-based materials.

This filler metal is also highly effective for dissimilar welding, enabling strong joints between stainless steel, carbon steel, and nickel alloys.

Chemical Composition of ERNiCrMo-10

The superior performance of ERNiCrMo-10 comes from its balanced alloy composition:

• Nickel (Ni): Balance
• Chromium (Cr): 20–22.5%
• Molybdenum (Mo): 12.5–14.5%
• Iron (Fe): 2–6%
• Tungsten (W): 2.5–3.5%

This composition delivers exceptional resistance to oxidation, corrosion, and thermal stress.
