Inconel 625

Product Description

Alloy **5 (UNS N****5)

Alloy **5 is a nickel-chromium-molybdenum alloy with an addition of niobium. The addition of molybdenum acts with the niobium to stiffen the alloy matrix, providing a high strength without a strengthening heat treatment. The alloy resists a wide range of corrosive environments and has a good resistance to pitting and crevice corrosion. Alloy **5 is used in chemical processing, aerospace and marine engineering oil & gas, pollution control equipment and nuclear reactors.

Characteristics

• Excellent mechanical properties at both extremely low and extremely high temperatures.
• Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.
• Almost complete freedom from chloride induced stress corrosion cracking.
• High resistance to oxidation at elevated temperatures up to ***0C.
• Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.

Applications

• Components where exposure to sea water and high mechanical stresses are required.
• Oil and gas production where hydrogen sulfide and elementary sulfur exist at temperature in excess of **0C.
• Components exposed to flue gas or in flue gas desulfurization plants.
• Flare stacks on offshore oil platforms.
• Hydrocarbon processing from tar-sand and oil-shale recovery projects.
