Steel 20CrMnTi Annealed vs 20CrMnTi Hot Rolled
Steel · 20CrMnTi temper comparison
20CrMnTi Annealed and 20CrMnTi Hot Rolled are two conditions of the same steel grade, 20CrMnTi: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 20CrMnTi Hot Rolled is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 400 MPa (58 ksi) for 20CrMnTi Annealed, about 25% more; tensile strength follows at 780 MPa (113 ksi) vs 620 MPa (89.9 ksi). In exchange, 20CrMnTi Annealed is the more ductile: elongation 22% versus 16% for 20CrMnTi Hot Rolled, and 20CrMnTi Hot Rolled is harder (225 HB vs 187 HB). On the shop floor, 20CrMnTi Annealed machines more easily (good vs fair).
20CrMnTi AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
20CrMnTi Hot RolledChoose it when strength drives the design.
20CrMnTi Annealed vs 20CrMnTi Hot Rolled: 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.
