Product Description
INCONEL alloy 690 is a high-chromium nickel alloy with excellent resistance to many corrosive aqueous media and high-temperature atmospheres. The alloy's high chromium content gives it excellent resistance to aqueous corrosion
by oxidizing acids (especially nitric acid) and salts, and to sulfidation at high-temperatures.In addition to its corrosion resistance, alloy 690 has high strength, good metallurgical stability and favorable fabrication characteristics.
