Product Details
Inconel 690 Nickel Alloy with Excellent Resistance to Corrosive
Aqueous Media
INCONEL 690 is a high-chromium nickel alloy having excellent
resistance to many corrosive aqueous media and hightemperature
atmospheres. In addition to its corrosion resistance, Inconel 690
has high strength, good metallurgical stability, and favorable
fabrication characteristics.
Chemical composition
Element | Ni | Cr | Fe | C | Si | Mn | S | Cu |
Weight(%) | 58.0 min | 27.0~31.0 | 7.0~11.0 | 0.05 max | 0.50 max | 0.50 max | 0.15 max | 0.50 max |
Advantages
- Excellent resistance to many corrosive aqueous media and
hightemperature atmospheres.
- High strength, good metallurgical stability, and favorable
fabrication characteristics.
- Outstanding resistance to oxidizing chemicals and to
high-temperature oxidizing gases.
- Resistance to stresscorrosion cracking in chloride-containing
environments as well as to sodium hydroxide solutions.
Application
- Inconel 690 is widely used for steam generator tubes, baffles,
tubesheets, and hardware in nuclear power generation.
- Useful for various applications involving nitric or
nitric/hydrofluoric acid solutions.
- Examples are tail-gas reheaters used in nitric acid production and
heating coils and tanks for Nitric/hydrofluoric solutions used in
pickling of stainless steels and reprocessing of nuclear fuels
- Coal-gasification units, burners and ducts for processing sulfuric
acid, furnaces for petrochemical processing, recuperators,
incinerators, and glass vitrification equipment for radioactive
waste disposal.
