Steel SUP10 Cold Drawn vs SUP10 Hot Rolled
Steel · SUP10 temper comparison
SUP10 Cold Drawn and SUP10 Hot Rolled are two conditions of the same steel grade, SUP10: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. SUP10 Cold Drawn is the stronger of the two: yield strength 800 MPa (116 ksi) against 560 MPa (81.2 ksi) for SUP10 Hot Rolled, about 43% more; tensile strength follows at 950 MPa (138 ksi) vs 900 MPa (131 ksi). In exchange, SUP10 Hot Rolled is the more ductile: elongation 14% versus 9% for SUP10 Cold Drawn, and SUP10 Cold Drawn is harder (280 HB vs 260 HB). SUP10 Hot Rolled runs hotter in service (200°C vs 180°C continuous). On the shop floor, SUP10 Cold Drawn machines more easily (good vs fair).
SUP10 Cold DrawnChoose it when strength drives the design, or when the part is machined in volume.
SUP10 Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUP10 Cold Drawn vs SUP10 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.

SUP10 Cold Drawn vs SUP10 Hot Rolled — frequently asked
Is SUP10 Cold Drawn stronger than SUP10 Hot Rolled?
Yes. SUP10 Cold Drawn has a typical yield strength of 800 MPa (116 ksi) against 560 MPa (81.2 ksi) for SUP10 Hot Rolled — about 43% more. Tensile strength is 950 MPa (138 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Rolled?
Annealed is the default SUP10 condition in the FabDigit quote flow (neither Cold Drawn nor Hot Rolled). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, SUP10 Cold Drawn or SUP10 Hot Rolled?
SUP10 Cold Drawn. Its machinability rates good (58/100) against fair (48/100) for SUP10 Hot Rolled; for welding the order is SUP10 Hot Rolled first (poor, 30/100) then SUP10 Cold Drawn (poor, 25/100).
