Steel 60Cr3 +C vs 60Cr3 +S
Steel · 60Cr3 temper comparison
60Cr3 +C and 60Cr3 +S are two conditions of the same steel grade, 60Cr3: +C (cold drawn) versus +S (treated for high shearability). The chemistry is identical, so every difference below comes from the condition. 60Cr3 +C is the stronger of the two: yield strength 660 MPa (95.7 ksi) against 420 MPa (60.9 ksi) for 60Cr3 +S, about 57% more; tensile strength follows at 850 MPa (123 ksi) vs 700 MPa (102 ksi). In exchange, 60Cr3 +S is the more ductile: elongation 19% versus 10% for 60Cr3 +C, and 60Cr3 +C is harder (240 HB vs 190 HB).
60Cr3 +CChoose it when strength drives the design.
60Cr3 +SChoose it when the part is bent, formed or impact-loaded.
60Cr3 +C vs 60Cr3 +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.

60Cr3 +C vs 60Cr3 +S — frequently asked
Is 60Cr3 +C stronger than 60Cr3 +S?
Yes. 60Cr3 +C has a typical yield strength of 660 MPa (95.7 ksi) against 420 MPa (60.9 ksi) for 60Cr3 +S — about 57% more. Tensile strength is 850 MPa (123 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, +C or +S?
+QT is the default 60Cr3 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, 60Cr3 +C or 60Cr3 +S?
60Cr3 +S. Its machinability rates good (60/100) against fair (52/100) for 60Cr3 +C; for welding the order is 60Cr3 +S first (poor, 25/100) then 60Cr3 +C (poor, 20/100).
