Steel 2083 Annealed vs 2083 Prehard
Steel · 2083 temper comparison
2083 Annealed and 2083 Prehard are two conditions of the same steel grade, 2083: Annealed versus Prehard (pre-hardened). The chemistry is identical, so every difference below comes from the condition. 2083 Prehard is the stronger of the two: yield strength 850 MPa (123 ksi) against 480 MPa (69.6 ksi) for 2083 Annealed, about 77% more; tensile strength follows at 1,000 MPa (145 ksi) vs 760 MPa (110 ksi). In exchange, 2083 Annealed is the more ductile: elongation 16% versus 12% for 2083 Prehard, and 2083 Prehard is harder (300 HB vs 230 HB). 2083 Prehard runs hotter in service (450°C vs 400°C continuous).
2083 AnnealedChoose it when the part is bent, formed or impact-loaded.
2083 PrehardChoose it when strength drives the design, or when the part sees heat.
2083 Annealed vs 2083 Prehard: 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.
