Steel 1012 Annealed vs 1012 Normalized
Steel · 1012 temper comparison
1012 Annealed and 1012 Normalized are two conditions of the same steel grade, 1012: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1012 Normalized is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 180 MPa (26.1 ksi) for 1012 Annealed, about 8% more; tensile strength follows at 345 MPa (50 ksi) vs 320 MPa (46.4 ksi). 1012 Normalized is harder — 100 HB against 90 HB for 1012 Annealed — which matters for wear surfaces and threads. On the shop floor, 1012 Annealed forms better (95 vs 85 out of 100).

1012 Annealed vs 1012 Normalized: 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.

1012 Annealed vs 1012 Normalized — frequently asked
Is 1012 Normalized stronger than 1012 Annealed?
Yes. 1012 Normalized has a typical yield strength of 195 MPa (28.3 ksi) against 180 MPa (26.1 ksi) for 1012 Annealed — about 8% more. Tensile strength is 345 MPa (50 ksi) vs 320 MPa (46.4 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
HR is the default 1012 condition in the FabDigit quote flow (neither Annealed nor Normalized). 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, 1012 Annealed or 1012 Normalized?
1012 Normalized, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 1012 Annealed.
