![]() The alloy is approved for pressure vessels in accordance with the American ASME Boiler and Pressure Vessel code up to temperatures of 900 ✯ (480 ºc) and to the German Pressure Vessel specification VdÜV –WBl.263 from 14-800 ✯ (-10-425 ºc). Nickel 400 can be used at elevated temperatures up to 1000✯ (538ºc) and has excellent mechanical properties down to -423 ✯ (-253 ºc). It is not recommended in oxidizing acids such as nitric and ammonia containing systems, due to the copper content of the alloy. The alloy can be used in non-oxidizing chloride solutions and is resistant to de-aerated hydrochloric and hydrofluoric acids. It is resistant to stress corrosion cracking which gives the alloy a wide range of potential applications in chemical and saltwater environments. The alloy can be hardened by cold work, has good weldability, and has excellent corrosion resistance in rapid flowing brackish or seawater. Nickel 400 is a solid solution alloy of Nickel and Copper (67% Ni, 23% Cu) which has outstanding corrosion resistance with extremely good mechanical properties even at cryogenic temperatures. 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. While tensile strength lessened at temperatures over 700☏, yield strength and elongation are only marginally reduced. ![]() Similarly, Nickel 400 retains many of its physical properties at high temperatures. Even when cooled to -423.17☏, Nickel Alloy 400 does not become brittle like many ferrous materials. This material is valued by many industries for its combination of high strength and corrosion resistance over a wide range of conditions and temperatures.
