Steel En26 Normalized vs En26-Z
Steel · En26 temper comparison
En26 Normalized and En26-Z are two conditions of the same steel grade, En26: Normalized versus Z (Q&T condition Z). The chemistry is identical, so every difference below comes from the condition. En26-Z is the stronger of the two: yield strength 1,350 MPa (196 ksi) against 620 MPa (89.9 ksi) for En26 Normalized, about 118% more; tensile strength follows at 1,620 MPa (235 ksi) vs 950 MPa (138 ksi). In exchange, En26 Normalized is the more ductile: elongation 14% versus 8% for En26-Z, and En26-Z is harder (470 HB vs 285 HB). En26 Normalized runs hotter in service (400°C vs 200°C continuous). On the shop floor, En26 Normalized machines more easily (fair vs poor).
En26 NormalizedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
En26-ZChoose it when strength drives the design.
En26 Normalized vs En26-Z: 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.

En26 Normalized vs En26-Z — frequently asked
Is En26-Z stronger than En26 Normalized?
Yes. En26-Z has a typical yield strength of 1,350 MPa (196 ksi) against 620 MPa (89.9 ksi) for En26 Normalized — about 118% more. Tensile strength is 1,620 MPa (235 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, Normalized or Z?
T is the default En26 condition in the FabDigit quote flow (neither Normalized nor Z). 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, En26 Normalized or En26-Z?
En26 Normalized. Its machinability rates fair (42/100) against poor (18/100) for En26-Z.
