What is Monel 400 sheet?

Monel 400 sheet is rolled nickel-copper alloy UNS N04400 supplied per ASTM B127 in thicknesses 0.5 to 4.75 mm. The alloy carries 63 percent minimum nickel and 28 to 34 percent copper, ships in hot-rolled annealed or cold-rolled annealed condition, and is specified for hydrofluoric acid service, brackish and marine duty, and concentrated sodium hydroxide vessels.

What is the difference between Monel 400 sheet and Monel 400 plate?

ASTM B127 sets the thickness break at 4.75 mm (0.1875 in). Product at or below 4.75 mm is classified as sheet; product above 4.75 mm is plate. Strip is a sub-form of sheet at 0.51 mm and thinner with a width ceiling of 610 mm. The chemistry, mechanical minima and certification regime are common across the three forms.

Can Monel 400 sheet be bent and formed?

Yes. Annealed Monel 400 sheet bends to a minimum inside radius of one thickness (1t) for 90 degree bends up to 3 mm and 1.5 t for 4 to 4.75 mm. Springback is higher than carbon steel because the elastic modulus is 179 GPa. The alloy work-hardens; cold reductions beyond 30 percent require an intermediate anneal at 870 to 980 degrees Celsius followed by water quench.

What is the typical Monel 400 sheet thickness?

Stocked Monel 400 sheet thicknesses are 0.5, 0.6, 0.8, 1.0, 1.2, 1.5, 2.0, 2.5, 3.0, 4.0 and 4.75 mm. Standard width is 1000, 1219 and 1500 mm; standard length is 2000, 2440, 3000 and 6000 mm. ASTM B127 tolerances apply by thickness band; full tolerance schedule on the product certificate.
