Steel 25MnCr5 Annealed vs 25MnCr5 Hot Rolled
Steel · 25MnCr5 temper comparison
25MnCr5 Annealed and 25MnCr5 Hot Rolled are two conditions of the same steel grade, 25MnCr5: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 25MnCr5 Hot Rolled is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 360 MPa (52.2 ksi) for 25MnCr5 Annealed, about 17% more; tensile strength follows at 680 MPa (98.6 ksi) vs 580 MPa (84.1 ksi). In exchange, 25MnCr5 Annealed is the more ductile: elongation 20% versus 17% for 25MnCr5 Hot Rolled, and 25MnCr5 Hot Rolled is harder (210 HB vs 190 HB).

25MnCr5 Annealed vs 25MnCr5 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.
