Steel 1112-ANN vs 1112-HR
Steel · 1112 temper comparison
1112-ANN and 1112-HR are two conditions of the same steel grade, 1112: ANN (annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1112-HR is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 230 MPa (33.4 ksi) for 1112-ANN, about 13% more; tensile strength follows at 440 MPa (63.8 ksi) vs 395 MPa (57.3 ksi). In exchange, 1112-ANN is the more ductile: elongation 30% versus 25% for 1112-HR, and 1112-HR is harder (121 HB vs 110 HB).
1112-ANNChoose it when the part is bent, formed or impact-loaded.
1112-HRChoose it when strength drives the design.
1112-ANN vs 1112-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.

1112-ANN vs 1112-HR — frequently asked
Is 1112-HR stronger than 1112-ANN?
Yes. 1112-HR has a typical yield strength of 260 MPa (37.7 ksi) against 230 MPa (33.4 ksi) for 1112-ANN — about 13% more. Tensile strength is 440 MPa (63.8 ksi) vs 395 MPa (57.3 ksi).
Which condition does FabDigit quote by default, ANN or HR?
CD is the default 1112 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 1112-ANN over 1112-HR?
Pick 1112-ANN when the part is bent, formed or impact-loaded. Pick 1112-HR when strength drives the design.
