INCONEL **1 ( UNS N****1 )

INCONEL nickel-chromium-iron alloy **1 is a general-purpose engineering material for applications that require resistance to heat and corrosion. The outstanding characteristic of INCONEL alloy **1 is its resistance to high-temperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined, and welded.

The composition is a face-centered-cubic solid solution with a high degree of metallurgical stability. The alloy’s nickel base, in conjunction with a substantial chromium content, provides resistance to many corrosive media and high-temperature environments. Oxidation resistance is further enhanced by the aluminum content.

Characteristics

• The most important property of Alloy **1 is resistance to oxidation at very high temperatures up to ***0C. Even under severe conditions such as, cyclical heating and cooling. This is possible due to Alloy **1 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.

Applications

• 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.
