Steel 6152 Cold Drawn vs 6152 Hot Rolled
Steel · 6152 temper comparison
6152 Cold Drawn and 6152 Hot Rolled are two conditions of the same steel grade, 6152: Cold Drawn versus Hot Rolled. 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 550 MPa (79.8 ksi) for 6152 Hot Rolled, about 27% more. In exchange, 6152 Hot Rolled is the more ductile: elongation 18% versus 12% for 6152 Cold Drawn, and 6152 Hot Rolled is harder (255 HB vs 240 HB). 6152 Hot Rolled runs hotter in service (300°C vs 250°C continuous). On the shop floor, 6152 Cold Drawn machines more easily (good vs fair).
6152 Cold DrawnChoose it when strength drives the design, or when the part is machined in volume.
6152 Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
6152 Cold Drawn vs 6152 Hot Rolled: 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.
