Steel 8617 Annealed vs 8617 Cold Drawn
Steel · 8617 temper comparison
8617 Annealed and 8617 Cold Drawn are two conditions of the same steel grade, 8617: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 8617 Cold Drawn is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 360 MPa (52.2 ksi) for 8617 Annealed, about 39% more; tensile strength follows at 600 MPa (87 ksi) vs 515 MPa (74.7 ksi). In exchange, 8617 Annealed is the more ductile: elongation 31% versus 18% for 8617 Cold Drawn, and 8617 Cold Drawn is harder (179 HB vs 149 HB).

8617 Cold DrawnChoose it when strength drives the design.
8617 Annealed vs 8617 Cold Drawn: 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.
