Nickel Alloy Monel 400 Cold Drawn vs Monel 400 Hot Finished
Nickel Alloy · Monel 400 temper comparison
Monel 400 Cold Drawn and Monel 400 Hot Finished are two conditions of the same nickel alloy grade, Monel 400: Cold Drawn versus Hot Finished (hot-rolled / hot-worked bar and plate, as-worked). The chemistry is identical, so every difference below comes from the condition. Monel 400 Cold Drawn is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 310 MPa (45 ksi) for Monel 400 Hot Finished, about 55% more; tensile strength follows at 690 MPa (100 ksi) vs 585 MPa (84.8 ksi). In exchange, Monel 400 Hot Finished is the more ductile: elongation 40% versus 25% for Monel 400 Cold Drawn, and Monel 400 Cold Drawn is harder (200 HB vs 150 HB).

Monel 400 Hot FinishedChoose it when the part is bent, formed or impact-loaded.
Monel 400 Cold Drawn vs Monel 400 Hot Finished: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Monel 400 Cold Drawn vs Monel 400 Hot Finished — frequently asked
Is Monel 400 Cold Drawn stronger than Monel 400 Hot Finished?
Yes. Monel 400 Cold Drawn has a typical yield strength of 480 MPa (69.6 ksi) against 310 MPa (45 ksi) for Monel 400 Hot Finished — about 55% more. Tensile strength is 690 MPa (100 ksi) vs 585 MPa (84.8 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Finished?
O is the default Monel 400 condition in the FabDigit quote flow (neither Cold Drawn nor Hot Finished). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Monel 400 Cold Drawn or Monel 400 Hot Finished?
Monel 400 Cold Drawn. Its machinability rates fair (38/100) against poor (32/100) for Monel 400 Hot Finished; for welding the order is Monel 400 Hot Finished first (very good, 80/100) then Monel 400 Cold Drawn (very good, 72/100).
