Steel 1022-CD vs 1022-HR

Steel · 1022 temper comparison

1022-CD and 1022-HR are two conditions of the same steel grade, 1022: CD (cold drawn) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1022-CD is the stronger of the two: yield strength 400 MPa (58 ksi) against 235 MPa (34.1 ksi) for 1022-HR, about 70% more; tensile strength follows at 475 MPa (68.9 ksi) vs 425 MPa (61.6 ksi). In exchange, 1022-HR is the more ductile: elongation 23% versus 15% for 1022-CD, and 1022-CD is harder (137 HB vs 121 HB).

1022-CDChoose it when strength drives the design.

1022-HRChoose it when the part is bent, formed or impact-loaded.

1022-CD vs 1022-HR — frequently asked

Is 1022-CD stronger than 1022-HR?

Yes. 1022-CD has a typical yield strength of 400 MPa (58 ksi) against 235 MPa (34.1 ksi) for 1022-HR — about 70% more. Tensile strength is 475 MPa (68.9 ksi) vs 425 MPa (61.6 ksi).

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

HR is the default 1022 condition in the FabDigit quote flow. 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, 1022-CD or 1022-HR?

1022-CD, by a small margin. Both rate good for machinability — 64/100 against 58/100 for 1022-HR.
