Alloy 601

Alloy 601 is a nickel-chromium alloy that offers outstanding oxidation resistance up to 1204°C

Alloy 601 alloy develops a tightly adherent oxide scale which resists spalling even under severe thermal cycling. This alloy has good high temperature strength and retains its ductility after long service exposure, with good corrosion resistance under oxidizing conditions.

Perfect for applications in the Thermal Processing industry

Alloy 601 can be used in a variety of applications including:

  • Copper brazing, annealing and sintering
  • Muffles and retorts
  • Radiant tubes
  • Strand annealing tubes
  • Steam superheater tube supports
  • Rotary kilns and calciners
  • Thermocouple protection tubes
  • Neclear waste transport tank lining
  • Vitrification of nuclear waste

About Alloy 601

Alloy 601 should be welded with a matching composition filler wire. In addition, the weld products developed for RA 602 CA® can provide a stronger weld with higher oxidation resistant than alloy 601.
