Steel E460K2 +C vs E460K2 +N
Steel · E460K2 temper comparison
E460K2 +C and E460K2 +N are two conditions of the same steel grade, E460K2: +C (cold drawn) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. E460K2 +C is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 490 MPa (71.1 ksi) for E460K2 +N, about 20% more; tensile strength follows at 700 MPa (102 ksi) vs 620 MPa (89.9 ksi). In exchange, E460K2 +N is the more ductile: elongation 21% versus 12% for E460K2 +C, and E460K2 +C is harder (220 HB vs 190 HB). E460K2 +N runs hotter in service (400°C vs 350°C continuous).

E460K2 +C vs E460K2 +N: 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.

E460K2 +C vs E460K2 +N — frequently asked
Is E460K2 +C stronger than E460K2 +N?
Yes. E460K2 +C has a typical yield strength of 590 MPa (85.6 ksi) against 490 MPa (71.1 ksi) for E460K2 +N — about 20% more. Tensile strength is 700 MPa (102 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, +C or +N?
+N is the default E460K2 condition in the FabDigit quote flow. 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, E460K2 +C or E460K2 +N?
E460K2 +C. Its machinability rates good (56/100) against fair (50/100) for E460K2 +N; for welding the order is E460K2 +N first (very good, 75/100) then E460K2 +C (very good, 70/100).
