ASTM B167 690 Nickel Alloy Tube

ASTM B167 690 Nickel Alloy Tube

Applications: coal gasification plants, burners and pipes for handling sulphuric acid; incinerators; petrochemical processing furnaces; steam generator pipes; applications involving nitric acid or nitric/hydrofluoric acid solutions.

Description

Inconel 690 (UNS N06690) is a high chromium-nickel alloy with excellent resistance to many corrosive aqueous media and high temperature atmospheres. Its high alloy content enables it to resist stress corrosion cracking in chloride-containing environments and in moderate concentrations of sodium hydroxide solutions. The high chromium content gives it excellent resistance to oxidising environments and high temperature oxidising gases. It also has high strength, good metallurgical stability and good fabrication characteristics.

Products Description

Alloy 690 is a high chromium-nickel alloy with excellent resistance to many corrosive aqueous media and high temperature atmospheres. The high chromium content of the alloy gives it excellent resistance to osmosis, metal chalking, oxidation and sulphidation at elevated temperatures. In addition to corrosion resistance, Alloy 690 offers high strength, good metallurgical stability and good fabrication characteristics.
