Steel Cr12MoV Annealed vs Cr12MoV Nitrided
Steel · Cr12MoV temper comparison
Cr12MoV Annealed and Cr12MoV Nitrided are two conditions of the same steel grade, Cr12MoV: Annealed versus Nitrided. The chemistry is identical, so every difference below comes from the condition. Cr12MoV Nitrided is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 460 MPa (66.7 ksi) for Cr12MoV Annealed, about 3.7 times as much; tensile strength follows at 2,000 MPa (290 ksi) vs 780 MPa (113 ksi). In exchange, Cr12MoV Annealed is the more ductile: elongation 12% versus 0.5% for Cr12MoV Nitrided, and Cr12MoV Nitrided is harder (1,100 HV vs 228 HV). Cr12MoV Nitrided runs hotter in service (450°C vs 200°C continuous). On the shop floor, Cr12MoV Annealed machines more easily (poor vs not recommended) and Cr12MoV Annealed welds better (poor vs not recommended).
Cr12MoV AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Cr12MoV NitridedChoose it when strength drives the design, or when the part sees heat.
Cr12MoV Annealed vs Cr12MoV 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.

Cr12MoV Annealed vs Cr12MoV Nitrided — frequently asked
Is Cr12MoV Nitrided stronger than Cr12MoV Annealed?
Yes. Cr12MoV Nitrided has a typical yield strength of 1,700 MPa (247 ksi) against 460 MPa (66.7 ksi) for Cr12MoV Annealed — about 3.7 times as much. Tensile strength is 2,000 MPa (290 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, Annealed or Nitrided?
Annealed is the default Cr12MoV 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, Cr12MoV Annealed or Cr12MoV Nitrided?
Cr12MoV Annealed. Its machinability rates poor (32/100) against not recommended (4/100) for Cr12MoV Nitrided; for welding the order is Cr12MoV Annealed first (poor, 15/100) then Cr12MoV Nitrided (not recommended, 3/100).
