Steel Ingot Iron Annealed vs Ingot Iron Cold Drawn
Steel · Ingot Iron temper comparison
Ingot Iron Annealed and Ingot Iron Cold Drawn are two conditions of the same steel grade, Ingot Iron: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. Ingot Iron Cold Drawn is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 150 MPa (21.8 ksi) for Ingot Iron Annealed, about 113% more; tensile strength follows at 380 MPa (55.1 ksi) vs 275 MPa (39.9 ksi). In exchange, Ingot Iron Annealed is the more ductile: elongation 45% versus 15% for Ingot Iron Cold Drawn, and Ingot Iron Cold Drawn is harder (110 HB vs 70 HB). On the shop floor, Ingot Iron Cold Drawn machines more easily (good vs fair).
Ingot Iron AnnealedChoose it when the part is bent, formed or impact-loaded.
Ingot Iron Cold DrawnChoose it when strength drives the design, or when the part is machined in volume.
Ingot Iron Annealed vs Ingot Iron 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.
