Steel 1010-CD vs 1010-HR
Steel · 1010 temper comparison
1010-CD and 1010-HR are two conditions of the same steel grade, 1010: CD (cold drawn) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1010-CD is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 180 MPa (26.1 ksi) for 1010-HR, about 69% more; tensile strength follows at 365 MPa (52.9 ksi) vs 325 MPa (47.1 ksi). In exchange, 1010-HR is the more ductile: elongation 28% versus 20% for 1010-CD, and 1010-CD is harder (105 HB vs 95 HB).
1010-CDChoose it when strength drives the design.
1010-HRChoose it when the part is bent, formed or impact-loaded.
1010-CD vs 1010-HR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1010-CD vs 1010-HR — frequently asked
Is 1010-CD stronger than 1010-HR?
Yes. 1010-CD has a typical yield strength of 305 MPa (44.2 ksi) against 180 MPa (26.1 ksi) for 1010-HR — about 69% more. Tensile strength is 365 MPa (52.9 ksi) vs 325 MPa (47.1 ksi).
Which condition does FabDigit quote by default, CD or HR?
HR is the default 1010 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.
When should I choose 1010-CD over 1010-HR?
Pick 1010-CD when strength drives the design. Pick 1010-HR when the part is bent, formed or impact-loaded.
