Incoloy® 825 / Inconel® Alloy 825

Properties of Incoloy® 825 / Inconel® Alloy 825

Incoloy® 825 offers exceptional resistance to sulfuric acid, phosphoric acid, nitric acid, organic acids, alkalis, and chloride-containing media. The molybdenum enhances resistance to pitting and crevice corrosion, while copper provides protection in reducing acids. The nickel component prevents stress corrosion, especially in chloride environments.

The alloy retains its mechanical properties in both low and high-temperature applications and demonstrates excellent structural stability. Due to its good workability, the material is suitable for welding, bending, and other industrial processes.

Incoloy® 825 is often chosen where conventional stainless steels fall short due to their limited acid resistance.

Applications of Incoloy® 825 / Inconel® Alloy 825

Incoloy® 825 is widely used in chemically aggressive environments where acid resistance, durability, and safety are essential. Examples of applications include:

• Chemical processing of acids such as sulfuric and phosphoric acid

• Oil and gas pipelines and components

• Equipment for acid production and pickling processes

• Equipment for nuclear fuel reprocessing

• Heat exchangers, pipelines, and tanks in corrosive installations

Due to its wide chemical resistance, Incoloy® 825 is a popular choice for process industries where corrosive media and high reliability are central.

Incoloy® 825 / Inconel® Alloy 825 is the ultimate solution for applications where strong corrosion resistance and structural durability converge.
