Steel A516 Annealed vs A516 Normalized
Steel · A516 temper comparison
A516 Annealed and A516 Normalized are two conditions of the same steel grade, A516: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. A516 Normalized is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 285 MPa (41.3 ksi) for A516 Annealed, about 16% more. A516 Normalized is harder — 163 HV against 150 HV for A516 Annealed — which matters for wear surfaces and threads.
A516 NormalizedChoose it when strength drives the design, or when surface hardness matters.
A516 Annealed vs A516 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.

A516 Annealed vs A516 Normalized — frequently asked
Is A516 Normalized stronger than A516 Annealed?
Yes. A516 Normalized has a typical yield strength of 330 MPa (47.9 ksi) against 285 MPa (41.3 ksi) for A516 Annealed — about 16% more. Tensile strength is 525 MPa (76.1 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
HR is the default A516 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, A516 Annealed or A516 Normalized?
A516 Annealed, by a small margin. Both rate good for machinability — 65/100 against 60/100 for A516 Normalized.
