Steel 20CrMnTi Annealed vs 20CrMnTi Normalized
Steel · 20CrMnTi temper comparison
20CrMnTi Annealed and 20CrMnTi Normalized are two conditions of the same steel grade, 20CrMnTi: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 20CrMnTi Normalized is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 400 MPa (58 ksi) for 20CrMnTi Annealed, about 20% more; tensile strength follows at 750 MPa (109 ksi) vs 620 MPa (89.9 ksi). In exchange, 20CrMnTi Annealed is the more ductile: elongation 22% versus 18% for 20CrMnTi Normalized, and 20CrMnTi Normalized is harder (217 HB vs 187 HB).

20CrMnTi Annealed vs 20CrMnTi Normalized: 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.
