Steel 60CrMo3-2 +C vs 60CrMo3-2 +S
Steel · 60CrMo3-2 temper comparison
60CrMo3-2 +C and 60CrMo3-2 +S are two conditions of the same steel grade, 60CrMo3-2: +C (cold drawn) versus +S (treated for high shearability). The chemistry is identical, so every difference below comes from the condition. 60CrMo3-2 +C is the stronger of the two: yield strength 820 MPa (119 ksi) against 430 MPa (62.4 ksi) for 60CrMo3-2 +S, about 91% more; tensile strength follows at 980 MPa (142 ksi) vs 720 MPa (104 ksi). In exchange, 60CrMo3-2 +S is the more ductile: elongation 20% versus 7% for 60CrMo3-2 +C, and 60CrMo3-2 +C is harder (290 HB vs 205 HB). 60CrMo3-2 +S runs hotter in service (400°C vs 250°C continuous). On the shop floor, 60CrMo3-2 +S machines more easily (good vs fair) and 60CrMo3-2 +S welds better (30 vs 20 out of 100).
60CrMo3-2 +CChoose it when strength drives the design.
60CrMo3-2 +SChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
60CrMo3-2 +C vs 60CrMo3-2 +S: 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.

60CrMo3-2 +C vs 60CrMo3-2 +S — frequently asked
Is 60CrMo3-2 +C stronger than 60CrMo3-2 +S?
Yes. 60CrMo3-2 +C has a typical yield strength of 820 MPa (119 ksi) against 430 MPa (62.4 ksi) for 60CrMo3-2 +S — about 91% more. Tensile strength is 980 MPa (142 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, +C or +S?
+QT is the default 60CrMo3-2 condition in the FabDigit quote flow (neither +C nor +S). 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, 60CrMo3-2 +C or 60CrMo3-2 +S?
60CrMo3-2 +S. Its machinability rates good (60/100) against fair (48/100) for 60CrMo3-2 +C; for welding the order is 60CrMo3-2 +S first (poor, 30/100) then 60CrMo3-2 +C (poor, 20/100).
