Description

Description

Overview:

Incoloy 800 is a rich alloy that houses top-notch chemical properties designed to withstand high-temperatures, add strength, as well as resist oxidation. It can also resist commonly occurring issues such as carburization or stress-deterioration.

This alloy is used for a range of applications that need corrosion-resistant features such as food processing or furnace equipment manufacturers. The high composition of nickel, which is a minimum 30 percent, ensures minimal embrittlement that happens due to sigma phase precipitation.

Key Features:

Impact Strength: Incoloy 800 flaunts impact resistant & high strength when kept at ideal room temperature. Not just that, the alloy remains particularly tough at the cryogenic temperatures.
Compressive Strength: The yield strength and compressive strength of Incoloy 800 are basically the same. This high compression resistance allows better moldability for the alloy.
Fatigue Strength: Alloy 800 houses ample fatigue strength, which means it doesn’t break down during molding and allows ample workability.
Machining: Incoloy 800 can readily be machined with the use of standard industrial methods.

Product Forms Available:

Coil: Ribbon, Foil, Strip

Applications:

Radiant Tubes
Muffles
Cracker Tubes
Trays for Heat Treatment
Manifolds
Furnace Equipment
Food Processing
Carburising Equipment
Heating Elements
Heat Exchangers

Possible Alternative Grades:

Inconel 718: Inconel 718 is used as an alternative for Incoloy 800, given its enhanced creep-rupture resistance properties.
Inconel 617: This particular alloy has optimum oxidation resistance properties when kept in a range of media known to be corrosive.
Inconel 625: Inconel 625 is an excellent alternative to Incoloy 800, given its ability to resist corrosion when exposed to acidic environments.

Frequently Asked Questions:

Is Incoloy 800 weldable?

Alloy 800 has amazing welding qualities. However, before the initiation of the welding process, the material needs to be cleaned thoroughly.

Does Incoloy 800 showcase nitridation resistance?

Incoloy 800 flaunts reasonable nitridation resistance when kept in a cracked ammonia environment. However, it falls short in terms of resistance when compared to Inconel 600.
