UNS# NO4400

Nickel 400 is a high-Nickel alloy consisting of at least 63% Nickel alloyed with Copper, some Iron, and other trace elements. This material is valued by many industries for its combination of high strength and corrosion resistance over a wide range of conditions and temperatures. Even when cooled to -423.17°F, Nickel Alloy 400 does not become brittle like many ferrous materials. Similarly, Nickel 400 retains many of its physical properties at high temperatures. While tensile strength lessened at temperatures over 700°F, yield strength and elongation are only marginally reduced.

Marine and chemical processing applications capitalize on the high corrosion resistance of this alloy and include piping systems, pump shafts, seawater valves, anchor cables, springs, heat exchangers, propeller shafts and fuel tanks.
