Steel 6152 Annealed vs 6152 Cold Drawn
Steel · 6152 temper comparison
6152 Annealed and 6152 Cold Drawn are two conditions of the same steel grade, 6152: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 6152 Cold Drawn is the stronger of the two: yield strength 700 MPa (102 ksi) against 415 MPa (60.2 ksi) for 6152 Annealed, about 69% more; tensile strength follows at 830 MPa (120 ksi) vs 670 MPa (97.2 ksi). In exchange, 6152 Annealed is the more ductile: elongation 23% versus 12% for 6152 Cold Drawn, and 6152 Cold Drawn is harder (240 HB vs 197 HB). 6152 Annealed runs hotter in service (400°C vs 250°C continuous).
6152 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
6152 Cold DrawnChoose it when strength drives the design.
6152 Annealed vs 6152 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.
