Steel 1.2510 Hot Rolled vs 1.2510 Stress Relieved
Steel · 1.2510 temper comparison
1.2510 Hot Rolled and 1.2510 Stress Relieved are two conditions of the same steel grade, 1.2510: Hot Rolled versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. 1.2510 Hot Rolled is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 440 MPa (63.8 ksi) for 1.2510 Stress Relieved, about 7% more; tensile strength follows at 780 MPa (113 ksi) vs 740 MPa (107 ksi). In exchange, 1.2510 Stress Relieved is the more ductile: elongation 16% versus 12% for 1.2510 Hot Rolled, and 1.2510 Hot Rolled is harder (18 HRC vs 16 HRC).
1.2510 Hot RolledChoose it when strength drives the design.
1.2510 Stress RelievedChoose it when the part is bent, formed or impact-loaded.
1.2510 Hot Rolled vs 1.2510 Stress Relieved: 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.
