Steel 1037-CD vs 1037-HR

Steel · 1037 temper comparison

1037-CD and 1037-HR are two conditions of the same steel grade, 1037: CD (cold drawn) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1037-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 282 MPa (40.9 ksi) for 1037-HR, about 77% more; tensile strength follows at 590 MPa (85.6 ksi) vs 510 MPa (74 ksi). In exchange, 1037-HR is the more ductile: elongation 26% versus 16% for 1037-CD, and 1037-CD is harder (170 HB vs 143 HB).

1037-CDChoose it when strength drives the design.

1037-HRChoose it when the part is bent, formed or impact-loaded.

1037-CD vs 1037-HR — frequently asked

Is 1037-CD stronger than 1037-HR?

Yes. 1037-CD has a typical yield strength of 500 MPa (72.5 ksi) against 282 MPa (40.9 ksi) for 1037-HR — about 77% more. Tensile strength is 590 MPa (85.6 ksi) vs 510 MPa (74 ksi).

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

HR is the default 1037 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, 1037-CD or 1037-HR?

1037-CD, by a small margin. Both rate good for machinability — 65/100 against 57/100 for 1037-HR; for welding the order is 1037-HR first (good, 58/100) then 1037-CD (fair, 52/100).
