Steel Cr12MoV Annealed vs Cr12MoV Hot Rolled/Forged
Steel · Cr12MoV temper comparison
Cr12MoV Annealed and Cr12MoV Hot Rolled/Forged are two conditions of the same steel grade, Cr12MoV: Annealed versus Hot Rolled/Forged (hot Rolled / Forged black bar). The chemistry is identical, so every difference below comes from the condition. Cr12MoV Hot Rolled/Forged is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 460 MPa (66.7 ksi) for Cr12MoV Annealed, about 35% more; tensile strength follows at 980 MPa (142 ksi) vs 780 MPa (113 ksi). In exchange, Cr12MoV Annealed is the more ductile: elongation 12% versus 7% for Cr12MoV Hot Rolled/Forged, and Cr12MoV Hot Rolled/Forged is harder (300 HB vs 217 HB). On the shop floor, Cr12MoV Annealed machines more easily (32 vs 18 out of 100).
Cr12MoV AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Cr12MoV Hot Rolled/ForgedChoose it when strength drives the design.
Cr12MoV Annealed vs Cr12MoV Hot Rolled/Forged: 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.
