Steel 1110-ANN vs 1110-HR
Steel · 1110 temper comparison
1110-ANN and 1110-HR are two conditions of the same steel grade, 1110: ANN (annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1110-HR is the stronger of the two: tensile strength 365 MPa (52.9 ksi) against 340 MPa (49.3 ksi) for 1110-ANN, about 7% more. In exchange, 1110-ANN is the more ductile: elongation 32% versus 28% for 1110-HR, and 1110-HR is harder (103 HB vs 95 HB).
1110-ANNChoose it when the part is bent, formed or impact-loaded.
1110-HRChoose it when strength drives the design.
1110-ANN vs 1110-HR: 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.

1110-ANN vs 1110-HR — frequently asked
Is 1110-HR stronger than 1110-ANN?
Yes. 1110-HR has a typical tensile strength of 365 MPa (52.9 ksi) against 340 MPa (49.3 ksi) for 1110-ANN — about 7% more.
Which condition does FabDigit quote by default, ANN or HR?
CD is the default 1110 condition in the FabDigit quote flow (neither ANN nor HR). 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, 1110-ANN or 1110-HR?
1110-HR. Its machinability rates very good (73/100) against good (68/100) for 1110-ANN.
