Monel 400 (UNS N04400)
Monel 400 (UNS N04400, W.Nr. 2.4360) is a nickel–copper alloy of roughly two-thirds nickel and one-third copper, single-phase across its whole composition range. It resists seawater, hydrofluoric acid, sulphuric acid and caustic alkalis, and holds its strength from sub-zero temperatures up to about 480 °C — which is why it is used for marine shafting, heat exchangers, HF alkylation plant and valve trim.
