Steel 1.2363 Annealed vs 1.2363 HT 58-60 HRC
Steel · 1.2363 temper comparison
1.2363 Annealed and 1.2363 HT 58-60 HRC are two conditions of the same steel grade, 1.2363: Annealed versus HT 58-60 HRC (hardened + tempered ~500 °C). The chemistry is identical, so every difference below comes from the condition. 1.2363 HT 58-60 HRC is the stronger of the two: yield strength 1,800 MPa (261 ksi) against 500 MPa (72.5 ksi) for 1.2363 Annealed, about 3.6 times as much; tensile strength follows at 2,050 MPa (297 ksi) vs 790 MPa (115 ksi). In exchange, 1.2363 Annealed is the more ductile: elongation 16% versus 2% for 1.2363 HT 58-60 HRC, and 1.2363 HT 58-60 HRC is harder (675 HV vs 230 HV). 1.2363 HT 58-60 HRC runs hotter in service (450°C vs 400°C continuous). On the shop floor, 1.2363 Annealed machines more easily (fair vs not recommended).

1.2363 Annealed vs 1.2363 HT 58-60 HRC: 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.
