Monel 400 (NA13, N04400)

Monel 400 (NA13, N04400) is a nickel-copper alloy with good strength and excellent corrosion resistance in a range of media especially sea water, hydrofluoric acid, sulfuric acid, and alkalis.

Although the grade can be tempered or cold worked to increase its properties, Monel 400 (2.4360) is supplied in the annealed condition as standard.

Monel 400 / NA13 is used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.

In the annealed condition Monel 400 / N04400 is an alloy that is easy to form and fabricate with no requirements for additional heat treatments to re-balance the alloy.
