Inconel 601

Inconel 601 (Inconel 601)

(UNS N06601) (EN 2.4851 - NiCr23Fe)

INCONEL® nickel-chromium-iron alloy 601 (UNS N06601/W.Nr. 2.4851) is a general-purpose engineering material for applications that require resistance to heat and corrosion. An outstanding characteristic of INCONEL alloy 601 is its resistance to hightemperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined and welded.

Alloy 601 is a nickel-chromium-iron alloy with additions of aluminum and titanium. Alloy 601 is characterized by:

  • Outstanding resistance to oxidation at high temperatures.
  • Good resistance to carburizing conditions.
  • Good resistance in oxidizing, sulfuric atmospheres.
