Why Inconel 690 ?

1. Excellent resistance to many corrosive aqueous media and hightemperature atmospheres.
2.High strength. good metallurqical stability, and favorable fabrication characteristics
3.outstanding resistance to oxidizina chemicals and to high-temperature oxidizina gases
4 Good resistance to stresscorrosion cracking in chloride-containing environments as wel as to sodium hvdroxide solutions

Inconel 690 Application field:

The alloy's resistance to sulfur-containing gases makes it an attractive material for such applications as coal-gasification units, burners and ducts for processing sulfuric acid, furnaces for petrochemical processing, recuperators, incinerators, and glass vitrification equipment for radioactive waste disposal. In various types of high-temperature water, alloy 690 displays low corrosion rates and excellent resistance to stress-corrosion cracking. Thus. alloy 690 is widely used for steam generator tubes, baffles, tubesheets, and hardware in nuclear power generation.
