Steel 1006-CD vs 1006-CR

Steel · 1006 temper comparison

1006-CD and 1006-CR are two conditions of the same steel grade, 1006: CD (cold drawn) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 1006-CD is the stronger of the two: yield strength 285 MPa (41.3 ksi) against 210 MPa (30.5 ksi) for 1006-CR, about 36% more. In exchange, 1006-CR is the more ductile: elongation 38% versus 20% for 1006-CD, and 1006-CD is harder (95 HB vs 88 HB).

1006-CDChoose it when strength drives the design.

1006-CRChoose it when the part is bent, formed or impact-loaded.

1006-CD vs 1006-CR — frequently asked

Is 1006-CD stronger than 1006-CR?

Yes. 1006-CD has a typical yield strength of 285 MPa (41.3 ksi) against 210 MPa (30.5 ksi) for 1006-CR — about 36% more. Tensile strength is 330 MPa (47.9 ksi) vs 315 MPa (45.7 ksi).

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

HR is the default 1006 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.

When should I choose 1006-CD over 1006-CR?

Pick 1006-CD when strength drives the design. Pick 1006-CR when the part is bent, formed or impact-loaded.
