Steel 1113-ANN vs 1113-HR
Steel · 1113 temper comparison
1113-ANN and 1113-HR are two conditions of the same steel grade, 1113: ANN (annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1113-HR is the stronger of the two: tensile strength 425 MPa (61.6 ksi) against 395 MPa (57.3 ksi) for 1113-ANN, about 8% more. In exchange, 1113-ANN is the more ductile: elongation 30% versus 25% for 1113-HR, and 1113-HR is harder (121 HB vs 111 HB). 1113-ANN runs hotter in service (400°C vs 350°C continuous).
1113-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1113-HRChoose it when strength drives the design.
1113-ANN vs 1113-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.

1113-ANN vs 1113-HR — frequently asked
Is 1113-HR stronger than 1113-ANN?
Yes. 1113-HR has a typical tensile strength of 425 MPa (61.6 ksi) against 395 MPa (57.3 ksi) for 1113-ANN — about 8% more.
Which condition does FabDigit quote by default, ANN or HR?
CD is the default 1113 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.
When should I choose 1113-ANN over 1113-HR?
Pick 1113-ANN when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 1113-HR when strength drives the design.
