Steel 1015 Annealed vs 1015 Normalized
Steel · 1015 temper comparison
1015 Annealed and 1015 Normalized are two conditions of the same steel grade, 1015: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1015 Normalized is the stronger of the two: yield strength 324 MPa (47 ksi) against 284 MPa (41.2 ksi) for 1015 Annealed, about 14% more; tensile strength follows at 424 MPa (61.5 ksi) vs 386 MPa (56 ksi). 1015 Normalized is harder — 121 HB against 111 HB for 1015 Annealed — which matters for wear surfaces and threads. On the shop floor, 1015 Annealed forms better (excellent vs very good).
1015 NormalizedChoose it when strength drives the design, or when surface hardness matters.
1015 Annealed vs 1015 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.

1015 Annealed vs 1015 Normalized — frequently asked
Is 1015 Normalized stronger than 1015 Annealed?
Yes. 1015 Normalized has a typical yield strength of 324 MPa (47 ksi) against 284 MPa (41.2 ksi) for 1015 Annealed — about 14% more. Tensile strength is 424 MPa (61.5 ksi) vs 386 MPa (56 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
HR is the default 1015 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, 1015 Annealed or 1015 Normalized?
1015 Normalized, by a small margin. Both rate fair for machinability — 54/100 against 48/100 for 1015 Annealed.
