Steel 1019-HR vs 1019-N
Steel · 1019 temper comparison
1019-HR and 1019-N are two conditions of the same steel grade, 1019: HR (hot rolled) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 1019-N is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 225 MPa (32.6 ksi) for 1019-HR, about 11% more; tensile strength follows at 430 MPa (62.4 ksi) vs 407 MPa (59 ksi). 1019-N is the more ductile: elongation 30% versus 25% for 1019-HR, and 1019-N is harder (138 HV vs 122 HV).
1019-NChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1019-HR vs 1019-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.

1019-HR vs 1019-N — frequently asked
Is 1019-N stronger than 1019-HR?
Yes. 1019-N has a typical yield strength of 250 MPa (36.3 ksi) against 225 MPa (32.6 ksi) for 1019-HR — about 11% more. Tensile strength is 430 MPa (62.4 ksi) vs 407 MPa (59 ksi).
Which condition does FabDigit quote by default, HR or N?
CD is the default 1019 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 1019-HR over 1019-N?
Pick 1019-N when strength drives the design, or when the part is bent, formed or impact-loaded.
