Steel 60Si2Mn Cold Drawn vs 60Si2Mn Hardened & Tempered
Steel · 60Si2Mn temper comparison
60Si2Mn Cold Drawn and 60Si2Mn Hardened & Tempered are two conditions of the same steel grade, 60Si2Mn: Cold Drawn versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 60Si2Mn Hardened & Tempered is the stronger of the two: yield strength 1,600 MPa (232 ksi) against 800 MPa (116 ksi) for 60Si2Mn Cold Drawn, about 100% more; tensile strength follows at 1,750 MPa (254 ksi) vs 1,000 MPa (145 ksi). In exchange, 60Si2Mn Cold Drawn is the more ductile: elongation 8% versus 6% for 60Si2Mn Hardened & Tempered, and 60Si2Mn Cold Drawn is harder (300 HB vs 255 HB). 60Si2Mn Hardened & Tempered runs hotter in service (250°C vs 200°C continuous). On the shop floor, 60Si2Mn Cold Drawn machines more easily (fair vs not recommended).
60Si2Mn Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
60Si2Mn Hardened & TemperedChoose it when strength drives the design, or when the part sees heat.
60Si2Mn Cold Drawn vs 60Si2Mn Hardened & Tempered: 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.

60Si2Mn Cold Drawn vs 60Si2Mn Hardened & Tempered — frequently asked
Is 60Si2Mn Hardened & Tempered stronger than 60Si2Mn Cold Drawn?
Yes. 60Si2Mn Hardened & Tempered has a typical yield strength of 1,600 MPa (232 ksi) against 800 MPa (116 ksi) for 60Si2Mn Cold Drawn — about 100% more. Tensile strength is 1,750 MPa (254 ksi) vs 1,000 MPa (145 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hardened & Tempered?
Annealed is the default 60Si2Mn condition in the FabDigit quote flow (neither Cold Drawn nor Hardened & Tempered). 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, 60Si2Mn Cold Drawn or 60Si2Mn Hardened & Tempered?
60Si2Mn Cold Drawn. Its machinability rates fair (50/100) against not recommended (12/100) for 60Si2Mn Hardened & Tempered; for welding the order is 60Si2Mn Cold Drawn first (poor, 18/100) then 60Si2Mn Hardened & Tempered (not recommended, 10/100).
