A material with excellent resistance to pitting, crevice and corrosion
cracking. 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.
Application
● 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.
