Steel En30B Annealed vs En30B Normalized
Steel · En30B temper comparison
En30B Annealed and En30B Normalized are two conditions of the same steel grade, En30B: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. En30B Normalized is the stronger of the two: yield strength 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for En30B Annealed, about 27% more; tensile strength follows at 950 MPa (138 ksi) vs 800 MPa (116 ksi). In exchange, En30B Annealed is the more ductile: elongation 20% versus 17% for En30B Normalized, and En30B Normalized is harder (285 HB vs 235 HB).
En30B AnnealedChoose it when the part is bent, formed or impact-loaded.
En30B NormalizedChoose it when strength drives the design.
En30B Annealed vs En30B 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.

En30B Annealed vs En30B Normalized — frequently asked
Is En30B Normalized stronger than En30B Annealed?
Yes. En30B Normalized has a typical yield strength of 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for En30B Annealed — about 27% more. Tensile strength is 950 MPa (138 ksi) vs 800 MPa (116 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
Cond W is the default En30B 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, En30B Annealed or En30B Normalized?
En30B Annealed, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for En30B Normalized; for welding the order is En30B Normalized first (poor, 25/100) then En30B Annealed (poor, 20/100).
