Abratig NiCr3
Inconel® 600/601/625 filler metal
Product description
Filler metal for gas-shielded TIG welding of high-nickel alloys, type Inconel 600* or Incoloy 800*, widely used in the construction of equipment subject to oxidizing and corrosive attack at very high temperatures. It is also extremely tough at low temperatures, making it ideal for use in cryogenics on 5% and 9% nickel steels. Perfectly suited to heterogeneous assemblies such as carbon or low-alloy steels with stainless or nickel-based steels, or even with some copper-based steels.

Why choose ABRATIG NiCr3 filler metal?
Choosing ABRATIG NiCr3 as a filler metal is an excellent option when working with nickel-based alloys, or when excellent resistance to heat, oxidation and corrosion is required. Here’s why this filler metal is often preferred:
- Excellent resistance to high temperatures
NiCr3 is designed for welding Inconel® 600/601/625 alloys and austenitic stainless steels in high-temperature environments. It holds up well up to around 1000°C without losing its mechanical properties.
–>Often used for furnace equipment, turbine components, heat exchangers, etc.
- Oxidation and chemical corrosion resistance
Thanks to its high nickel and chromium content, TIG NiCr3 :
-Excellent resistance to hot oxidation,
-withstands acid, chlorine and sulfur environments,
-is ideal for petrochemical, marine or aggressive environments.
- Welding dissimilar metals
This filler metal is often used as a transition between :
-carbon steel and stainless steel,
-stainless steel and a nickel alloy,
-or to repair composite parts in special alloys.
–> It avoids problems of cracking or galvanic corrosion between different materials.
- Stable, tenacious structure
Welds made with NiCr3 remain ductile, stable over the long term, and resist creep well, even under high thermal stress.
