Steel 25MnCr5 Cold Drawn vs 25MnCr5 Hot Rolled
Steel · 25MnCr5 temper comparison
25MnCr5 Cold Drawn and 25MnCr5 Hot Rolled are two conditions of the same steel grade, 25MnCr5: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 25MnCr5 Cold Drawn is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 420 MPa (60.9 ksi) for 25MnCr5 Hot Rolled, about 38% more; tensile strength follows at 750 MPa (109 ksi) vs 680 MPa (98.6 ksi). In exchange, 25MnCr5 Hot Rolled is the more ductile: elongation 17% versus 10% for 25MnCr5 Cold Drawn, and 25MnCr5 Cold Drawn is harder (225 HB vs 210 HB). On the shop floor, 25MnCr5 Cold Drawn machines more easily (good vs fair).
25MnCr5 Cold DrawnChoose it when strength drives the design, or when the part is machined in volume.
25MnCr5 Hot RolledChoose it when the part is bent, formed or impact-loaded.
25MnCr5 Cold Drawn 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.
