Steel WC11-ANN vs WC11 N+T
Steel · WC11 temper comparison
WC11-ANN and WC11 N+T are two conditions of the same steel grade, WC11: ANN (annealed) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. WC11 N+T is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 310 MPa (45 ksi) for WC11-ANN, about 34% more; tensile strength follows at 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi). In exchange, WC11-ANN is the more ductile: elongation 26% versus 22% for WC11 N+T, and WC11 N+T is harder (190 HB vs 155 HB).

WC11-ANN vs WC11 N+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.

WC11-ANN vs WC11 N+T — frequently asked
Is WC11 N+T stronger than WC11-ANN?
Yes. WC11 N+T has a typical yield strength of 415 MPa (60.2 ksi) against 310 MPa (45 ksi) for WC11-ANN — about 34% more. Tensile strength is 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, ANN or N+T?
N+T is the default WC11 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, WC11-ANN or WC11 N+T?
WC11-ANN, by a small margin. Both rate good for machinability — 63/100 against 55/100 for WC11 N+T; for welding the order is WC11-ANN first (good, 68/100) then WC11 N+T (good, 60/100).
