Steel 1113-ANN vs 1113 CDSR
Steel · 1113 temper comparison
1113-ANN and 1113 CDSR are two conditions of the same steel grade, 1113: ANN (annealed) versus CDSR (cold Drawn, Stress Relieved). The chemistry is identical, so every difference below comes from the condition. 1113 CDSR is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 225 MPa (32.6 ksi) for 1113-ANN, about 71% more; tensile strength follows at 480 MPa (69.6 ksi) vs 395 MPa (57.3 ksi). In exchange, 1113-ANN is the more ductile: elongation 30% versus 13% for 1113 CDSR, and 1113 CDSR is harder (163 HB vs 111 HB). 1113-ANN runs hotter in service (400°C vs 350°C continuous). On the shop floor, 1113 CDSR machines more easily (excellent vs very good).
1113-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1113 CDSRChoose it when strength drives the design, or when the part is machined in volume.
1113-ANN vs 1113 CDSR: 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.

1113-ANN vs 1113 CDSR — frequently asked
Is 1113 CDSR stronger than 1113-ANN?
Yes. 1113 CDSR has a typical yield strength of 385 MPa (55.8 ksi) against 225 MPa (32.6 ksi) for 1113-ANN — about 71% more. Tensile strength is 480 MPa (69.6 ksi) vs 395 MPa (57.3 ksi).
Which condition does FabDigit quote by default, ANN or CDSR?
CD is the default 1113 condition in the FabDigit quote flow (neither ANN nor CDSR). 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, 1113-ANN or 1113 CDSR?
1113 CDSR. Its machinability rates excellent (92/100) against very good (82/100) for 1113-ANN.
