Steel CPM 10V Annealed vs CPM 10V Nitrided
Steel · CPM 10V temper comparison
CPM 10V Annealed and CPM 10V Nitrided are two conditions of the same steel grade, CPM 10V: Annealed versus Nitrided. The chemistry is identical, so every difference below comes from the condition. CPM 10V Nitrided is the stronger of the two: yield strength 1,750 MPa (254 ksi) against 560 MPa (81.2 ksi) for CPM 10V Annealed, about 3.1 times as much; tensile strength follows at 2,000 MPa (290 ksi) vs 830 MPa (120 ksi). In exchange, CPM 10V Annealed is the more ductile: elongation 12% versus 1% for CPM 10V Nitrided, and CPM 10V Nitrided is harder (61 HRC vs 24 HRC). On the shop floor, CPM 10V Annealed machines more easily (poor vs not recommended) and CPM 10V Annealed welds better (poor vs not recommended).
CPM 10V AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
CPM 10V NitridedChoose it when strength drives the design.
CPM 10V Annealed vs CPM 10V Nitrided: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel 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.

CPM 10V Annealed vs CPM 10V Nitrided — frequently asked
Is CPM 10V Nitrided stronger than CPM 10V Annealed?
Yes. CPM 10V Nitrided has a typical yield strength of 1,750 MPa (254 ksi) against 560 MPa (81.2 ksi) for CPM 10V Annealed — about 3.1 times as much. Tensile strength is 2,000 MPa (290 ksi) vs 830 MPa (120 ksi).
Which condition does FabDigit quote by default, Annealed or Nitrided?
Annealed is the default CPM 10V condition in the FabDigit quote flow. 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, CPM 10V Annealed or CPM 10V Nitrided?
CPM 10V Annealed. Its machinability rates poor (25/100) against not recommended (2/100) for CPM 10V Nitrided; for welding the order is CPM 10V Annealed first (poor, 15/100) then CPM 10V Nitrided (not recommended, 3/100).
