Ni 61.0, Cr 21.5, Mo 9.0, Nb+Ta 3.6

Inconel 625 in this grade in the following forms: Bar, square bar, wire cuts, sheet, plate, tube, pipe, fastener, disk, machined, forged.

Overview

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.
