Steel En26 Annealed vs En26 Normalized

Steel · En26 temper comparison

En26 Annealed and En26 Normalized are two conditions of the same steel grade, En26: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. En26 Normalized is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 450 MPa (65.3 ksi) for En26 Annealed, about 38% more; tensile strength follows at 950 MPa (138 ksi) vs 700 MPa (102 ksi). In exchange, En26 Annealed is the more ductile: elongation 22% versus 14% for En26 Normalized, and En26 Normalized is harder (285 HB vs 205 HB). En26 Annealed runs hotter in service (450°C vs 400°C continuous). On the shop floor, En26 Annealed machines more easily (good vs fair).

En26 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

En26 NormalizedChoose it when strength drives the design.

En26 Annealed vs En26 Normalized — frequently asked

Is En26 Normalized stronger than En26 Annealed?

Yes. En26 Normalized has a typical yield strength of 620 MPa (89.9 ksi) against 450 MPa (65.3 ksi) for En26 Annealed — about 38% more. Tensile strength is 950 MPa (138 ksi) vs 700 MPa (102 ksi).

Which condition does FabDigit quote by default, Annealed or Normalized?

T is the default En26 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, En26 Annealed or En26 Normalized?

En26 Annealed. Its machinability rates good (55/100) against fair (42/100) for En26 Normalized; for welding the order is En26 Annealed first (fair, 35/100) then En26 Normalized (poor, 28/100).
