Alloy 825

About Alloy 825

Incoloy® 825, designated as Nickel Alloy 825, is a nickel–iron–chromium alloy containing minor proportions of molybdenum, copper and titanium. This composition provides Incoloy® 825 with enhanced resistance to corrosion in highly aggressive environments.

Like many other alloys in the Incoloy family, Alloy 825 offers the user a range of measurable advantages:

Effective resistance to both reducing and oxidising acids, such as sulphuric and phosphoric acid

Reduces the incidence of stress corrosion cracking

Prevents localised attacks, including pitting and crevice corrosion

Provides consistent resistance to multiple oxidising agents, including nitric acid, nitrates and oxidising salts

Due to its enhanced corrosion resistance, Incoloy® 825 is utilised in several industries and applications:

Chemical processing

Pollution control

Refrigeration systems

Oil and gas recovery

Hot containers for food, water and seawater

Acid manufacturing

Pickling tank heaters, tanks and associated equipment

Reprocessing of nuclear fuel

Handling of radioactive waste

Ship exhaust systems
