Steel 1005-HR vs 1005-N
Steel · 1005 temper comparison
1005-HR and 1005-N are two conditions of the same steel grade, 1005: HR (hot rolled) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 1005-N is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 180 MPa (26.1 ksi) for 1005-HR, about 6% more. 1005-N is the more ductile: elongation 33% versus 28% for 1005-HR, and 1005-HR is harder (95 HB vs 90 HB).
1005-NChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1005-HR vs 1005-N: 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.

1005-HR vs 1005-N — frequently asked
Is 1005-N stronger than 1005-HR?
Yes. 1005-N has a typical yield strength of 190 MPa (27.6 ksi) against 180 MPa (26.1 ksi) for 1005-HR — about 6% more. Tensile strength is 310 MPa (45 ksi) vs 320 MPa (46.4 ksi).
Which condition does FabDigit quote by default, HR or N?
CD is the default 1005 condition in the FabDigit quote flow (neither HR nor N). 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 1005-HR over 1005-N?
Pick 1005-N when strength drives the design, or when the part is bent, formed or impact-loaded.
