API 6A Inconel625 Inconel 625/UNS N06625/2.4856/Alloy 625/NCF 625/AMS 5666 Forged Forging Steel Seamless Rolled Rings

We are professional API 6A Inconel625 Inconel 625(UNS N06625, 2.4856, Alloy 625,NCF 625,AMS 5666)Forged Forging Steel Seamless Rolled Rings from china

Inconel 625 is a material with excellent resistance to pitting, crevice and corrosion cracking. Inconel 625 is highly resistant in a wide range of organic and mineral acids. Good high temperature strength.

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 1050C.

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 150C.

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.
