 Characteristics

• The most important property of Alloy 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 Alloy 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.

 

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.
