Alloy 400 / 2.4360

Alloy 400has outstanding resistance to neutral and alkaline salt solutions. This alloy is one of the few metallic materials which can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives. It has been a standard material for salt plants for many years. 2.4360 has good mechanical properties from sub-zero temperatures up to about 550 °C and is free from chloride induced stress-corrosion cracking.

Main fields of application of alloy 400

2.4360 is a single-phase solid-solution nickel-copper alloy with excellent corrosion resistance to a wide range of media. Typical applications include:

- propeller and pump shafts for seawater service

- industrial heat exchangers

- brine heaters and evaporator bodies in seawater desalination plants

- feed-water and steam generator tubing in power plants

- plants for uranium refining and isotope separation in the production of nuclear fuel

- sulphuric and hydrofluoric acid alkylation plants

- splash-zone sheathing in offshore structures

- cladding for crude oil distillation columns
