Inconel Bar

Inconel Bar has varying grades that have specific designation and uses in certain areas, parts, or structures.

InconelThere is a general purpose intended for this type of alloy grades. Primarily this nickel alloy is used for structural engineering parts and components that are used at high temperatures where stability, durability, and strength are significant.

Inconel belongs to the group of austenitic nickel-chromium-based superalloys, with the trademark of Special Metals Corporation. These alloys are types of materials that are highly resistant to corrosion and oxidation in extreme environments where excessive pressure and heat are present.

This alloy Inconel bar, when heated, forms a passiavting oxide layer that protects its outer surface from further attack – making them stand across a wide temperature range and high-temperature applications. Precipitation strengthening and solid solution strengthening develop the alloy’s high-temperature strength. These alloys are really very resistant against attack from hot gases and oxidizing chemicals.

Hence, Inconel and its varying grades are applied in duct work, furnaces, high-temperature burners, and petrochemical heaters.

Please see the Inconel table below for more information about the various grades and their specific properties and applications.
