Steel 1008 Annealed vs 1008 Normalized
Steel · 1008 temper comparison
1008 Annealed and 1008 Normalized are two conditions of the same steel grade, 1008: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1008 Normalized is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 170 MPa (24.7 ksi) for 1008 Annealed, about 15% more; tensile strength follows at 325 MPa (47.1 ksi) vs 295 MPa (42.8 ksi). In exchange, 1008 Annealed is the more ductile: elongation 40% versus 33% for 1008 Normalized, and 1008 Normalized is harder (90 HB vs 85 HB).
1008 AnnealedChoose it when the part is bent, formed or impact-loaded.
1008 NormalizedChoose it when strength drives the design.
1008 Annealed vs 1008 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.

1008 Annealed vs 1008 Normalized — frequently asked
Is 1008 Normalized stronger than 1008 Annealed?
Yes. 1008 Normalized has a typical yield strength of 195 MPa (28.3 ksi) against 170 MPa (24.7 ksi) for 1008 Annealed — about 15% more. Tensile strength is 325 MPa (47.1 ksi) vs 295 MPa (42.8 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
HR is the default 1008 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, 1008 Annealed or 1008 Normalized?
1008 Normalized, by a small margin. Both rate fair for machinability — 44/100 against 38/100 for 1008 Annealed.
