Steel 08F-CD vs 08F Normalized

Steel · 08F temper comparison

08F-CD and 08F Normalized are two conditions of the same steel grade, 08F: CD (cold drawn) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 08F-CD is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 205 MPa (29.7 ksi) for 08F Normalized, about 80% more; tensile strength follows at 450 MPa (65.3 ksi) vs 335 MPa (48.6 ksi). In exchange, 08F Normalized is the more ductile: elongation 37% versus 15% for 08F-CD, and 08F-CD is harder (140 HB vs 110 HB). 08F Normalized runs hotter in service (425°C vs 300°C continuous).

08F-CDChoose it when strength drives the design.

08F NormalizedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

08F-CD vs 08F Normalized — frequently asked

Is 08F-CD stronger than 08F Normalized?

Yes. 08F-CD has a typical yield strength of 370 MPa (53.7 ksi) against 205 MPa (29.7 ksi) for 08F Normalized — about 80% more. Tensile strength is 450 MPa (65.3 ksi) vs 335 MPa (48.6 ksi).

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

CR-Annealed is the default 08F condition in the FabDigit quote flow (neither CD 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, 08F-CD or 08F Normalized?

08F-CD. Its machinability rates good (55/100) against fair (48/100) for 08F Normalized; for welding the order is 08F Normalized first (excellent, 95/100) then 08F-CD (excellent, 90/100).
