Steel EN36-CD vs EN36-CR

Steel · EN36 temper comparison

EN36-CD and EN36-CR are two conditions of the same steel grade, EN36: CD (cold drawn) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. EN36-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 560 MPa (81.2 ksi) for EN36-CR, about 11% more; tensile strength follows at 810 MPa (117 ksi) vs 760 MPa (110 ksi). On the shop floor, EN36-CR forms better (fair vs poor).

EN36-CD vs EN36-CR — frequently asked

Is EN36-CD stronger than EN36-CR?

Yes. EN36-CD has a typical yield strength of 620 MPa (89.9 ksi) against 560 MPa (81.2 ksi) for EN36-CR — about 11% more. Tensile strength is 810 MPa (117 ksi) vs 760 MPa (110 ksi).

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

HR is the default EN36 condition in the FabDigit quote flow (neither CD nor CR). 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, EN36-CD or EN36-CR?

EN36-CD, by a small margin. Both rate fair for machinability — 52/100 against 47/100 for EN36-CR.
