Inconel alloy 690 is a high chromium Inconel with excellent resistance to many corrosive aqueous media and high temperature atmosphere. Its high chromium content gives it excellent resistance to aqueous corrosion by oxidising acids (especially nitric acid) and salts and to sulphidation at high temperatures. In addition to its corrosion resistance, Alloy 690 has high strength, good metallurgical stability and favourable fabrication characteristics.
