Steel 1.2510 Annealed vs 1.2510 Hot Rolled
Steel · 1.2510 temper comparison
1.2510 Annealed and 1.2510 Hot Rolled are two conditions of the same steel grade, 1.2510: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Both yield at about 450 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus Hot Rolled). 1.2510 Annealed is the more ductile: elongation 15% versus 12% for 1.2510 Hot Rolled, and 1.2510 Hot Rolled is harder (18 HRC vs 16 HRC).
1.2510 AnnealedChoose it when the part is bent, formed or impact-loaded.
1.2510 Annealed vs 1.2510 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.
