Product description

ABRATIG NiCrFe-12 is a nickel-chromium-iron alloy filler metal.

This welding wire has high oxidation resistance, excellent high-temperature strength and very good corrosion resistance in case-hardening media. The 2.4649 filler metal is suitable for operating temperatures up to 1200°C and is therefore mainly used in the high-temperature range.

Product application instructions

  • Boilers, turbines, exchangers,

  • High-pressure or high-temperature piping,

  • Nuclear, chemical and petrochemical industries,

  • Protective coatings in high-stress areas,

  • Connections between dissimilar materials (e.g. stainless steel 304 → Inconel 625).

Mechanical characteristics

Why choose ABRATIG NiCrFe12 filler metal?

ABRATIG NiCrFe12 filler metal meets the most demanding requirements in terms of mechanical strength, corrosion resistance and high-temperature stability.

Here’s why we opt for NiCrFe-12 TIG:

  1. Excellent corrosion resistance

Thanks to its nickel-chromium-iron composition, it is extremely resistant to wear:

  • to generalized corrosion,
  • to oxidizing and reducing environments,
  • to stress corrosion, particularly in acidic and saline environments.
  1. Excellent high-temperature resistance

NiCrFe-12 is designed to operate in extreme thermal environments, with good stability up to 900-1000°C, or even higher depending on the application. It retains its mechanical properties even after long thermal cycles.

  1. Resistance to mechanical stress

It has good toughness and high impact strength, and is highly resistant to creep at high temperatures – ideal for parts subjected to prolonged stress under severe conditions.

  1. Ideal filler metal for dissimilar assemblies

NiCrFe-12 is often used to weld different materials together, such as :

  • stainless steel → nickel,
  • steel → stainless steel,
  • steel → nickel,
  • or special alloys between them.

This makes it a popular “buffer filler metal” for maintenance, repair and heterogeneous construction.
