Steel 1.2080 Annealed vs 1.2080 Q&T 60-62 HRC
Steel · 1.2080 temper comparison
1.2080 Annealed and 1.2080 Q&T 60-62 HRC are two conditions of the same steel grade, 1.2080: Annealed versus Q&T 60-62 HRC (oil quench + 200-230 °C temper). The chemistry is identical, so every difference below comes from the condition. 1.2080 Q&T 60-62 HRC is the stronger of the two: tensile strength 2,150 MPa (312 ksi) against 850 MPa (123 ksi) for 1.2080 Annealed, about 153% more. In exchange, 1.2080 Annealed is the more ductile: elongation 12% versus 1% for 1.2080 Q&T 60-62 HRC, and 1.2080 Q&T 60-62 HRC is harder (61 HRC vs 20 HRC). 1.2080 Annealed runs hotter in service (200°C vs 180°C continuous). On the shop floor, 1.2080 Annealed machines more easily (poor vs not recommended).

1.2080 Annealed vs 1.2080 Q&T 60-62 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.
