What is Monel 400 plate?

Monel 400 plate is a hot-rolled or cold-rolled flat product of the nickel-copper alloy UNS N04400 supplied to ASTM B127. The plate ships annealed with a typical thickness range of 3 mm to 80 mm, width to 1500 mm and length to 6000 mm. Plate is the input stock for HF acid vessels, heat exchanger tube sheets, marine bulkhead and caustic storage.

What sizes and thicknesses of Monel 400 plate are available?

TorqBolt stocks Monel 400 plate from 3 mm to 80 mm thickness, 1000 mm to 1500 mm width and lengths to 6000 mm. Thin gauge below 5 mm is treated as sheet under the same ASTM B127 envelope. Hot-rolled mill plate, cold-rolled bright sheet, pickled and ground surfaces all available; sawn, sheared or waterjet edges to drawing.

Does Monel 400 plate need NACE MR0175 certification for sour service?

For H2S sour service, Monel 400 plate must clear NACE MR0175 / ISO 15156-3 with a hardness ceiling of 35 HRC for the nickel-copper alloy group. Annealed B127 plate measures 110 to 149 HB (about 75 HRB), well below the cap. Sour-service shipments ship with EN 10204 type 3.2 plus the NACE compliance statement on the MTC.

Why is Monel 400 plate more expensive than SS 316L plate?

Monel 400 carries 63 to 70 percent nickel and 28 to 34 percent copper against 10 to 14 percent nickel in 316L, so the LME nickel and copper input cost alone runs 4 to 6 times higher per kilogram. The alloy is also melted in smaller heats, which raises mill conversion cost. The price gap pays back in HF acid, brackish water and caustic service where 316L fails.
