Steel SUP10 Cold Drawn vs SUP10 Q&T
Steel · SUP10 temper comparison
SUP10 Cold Drawn and SUP10 Q&T are two conditions of the same steel grade, SUP10: Cold Drawn versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. SUP10 Q&T is the stronger of the two: yield strength 1,300 MPa (189 ksi) against 800 MPa (116 ksi) for SUP10 Cold Drawn, about 63% more; tensile strength follows at 1,450 MPa (210 ksi) vs 950 MPa (138 ksi). SUP10 Q&T is harder — 415 HB against 280 HB for SUP10 Cold Drawn — which matters for wear surfaces and threads. SUP10 Q&T runs hotter in service (230°C vs 180°C continuous). On the shop floor, SUP10 Cold Drawn machines more easily (good vs poor), SUP10 Cold Drawn welds better (poor vs not recommended), and SUP10 Cold Drawn forms better (poor vs not recommended).
SUP10 Cold DrawnChoose it when the part is machined in volume, or when it will be welded.
SUP10 Q&TChoose it when strength drives the design, or when surface hardness matters.
SUP10 Cold Drawn vs SUP10 Q&T: 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 Q&T — frequently asked
Is SUP10 Q&T stronger than SUP10 Cold Drawn?
Yes. SUP10 Q&T has a typical yield strength of 1,300 MPa (189 ksi) against 800 MPa (116 ksi) for SUP10 Cold Drawn — about 63% more. Tensile strength is 1,450 MPa (210 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Q&T?
Annealed is the default SUP10 condition in the FabDigit quote flow (neither Cold Drawn nor Q&T). 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 Q&T?
SUP10 Cold Drawn. Its machinability rates good (58/100) against poor (25/100) for SUP10 Q&T; for welding the order is SUP10 Cold Drawn first (poor, 25/100) then SUP10 Q&T (not recommended, 10/100).
