Nickel 400 Alloy Details
Nickel 400 is 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.
The alloy can be hardened by cold work, has good weldability and has excellent corrosion resistance in rapid flowing brackish or sea water.
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 used in non-oxidizing chloride solutions and is resistant to de-aerated hydrochloric and hydrofluoric acids.
It is not recommended in oxidizing acids such as nitric and ammonia containing systems, due to the copper content of the alloy.
Nickel 400 can be used at elevated temperatures up to 1000ºF (538ºc) and has excellent mechanical properties down to -423 ºF (-253 ºc).
The alloy is approved for pressure vessels accordance to the American ASME Boiler and Pressure Vessel code up to temperatures of 900 ºF (480 ºc) and to the German Pressure Vessel specification VdÜV –WBl.263 from 14-800 ºF (-10-425 ºc).
