Inconel 690 Wire

Inconel 690 Wire is a high-chromium nickel alloy having excellent resistance to many corrosive aqueous media and high temperature atmospheres. In addition to its corrosion resistance, Inconel 690 Wire has high strength, good metallurgical stability, and favorable fabrication characteristics.

The substantial chromium content gives the alloy outstanding resistance to oxidizing chemicals and to high-temperature oxidizing gases. The high level of nickel imparts resistance to stress corrosion cracking in chloride-containing environments as well as to sodium hydroxide solutions. In various types of high-temperature water, Inconel 690 Wire displays low corrosion rates and excellent resistance to stress-corrosion cracking.
