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.
The most important property of Inconel 601 is resistance to oxidation at very high temperatures up to 1250C. Even under severe conditions such as， cyclical heating and cooling. This is possible due to Inconel 601 having a tightly adherent oxide layer which is resistant against spalling. Resistance to carburization is good， also resistant to carbon nitriding conditions. Due to high chromium and some aluminum content， good resistance in oxidizing sulfur bearing atmospheres at elevated temperatures is demonstrated.
Application
- Trays， baskets and fixtures used in various heat treatments such as carburizing and carbon nitriding.
- Refractory anchors， strand annealing and radiant tubes， high velocity gas burners， wire mesh belts etc.
- Insulating cans in ammonia reformers and catalyst support grids used in nitric acid production.
- Thermal reactors in exhaust system of petrol engines.
- Fabricated combustion chambers.
- Tube supports and ash trays in the power generation industry.

Heat Treatment
Inconel 601 is solution annealed at 1100 – 1180°C， and cooled quickly so as to avoid sensitisation to intergranular corrosion. Annealing time should be short to avoid excessive grain growth.
Corrosion Resistance
Inconel 601 has excellent corrosion resistance to the mineral acids， similar to Inconel 600. Inconel 601 has good resistance to sodium hydroxide solutions and because of the high nickel content good resistance to chloride stress corrosion cracking. As with austenitic stainless steels Inconel 601 can be sensitised to intergranular corrosion in some aggressive media after heating in the temperature range 540 – 760°C.
