Steel DP590-BH vs DP590-HR
Steel · DP590 temper comparison
DP590-BH and DP590-HR are two conditions of the same steel grade, DP590: BH (bake-hardened) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. DP590-BH is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 400 MPa (58 ksi) for DP590-HR, about 15% more. In exchange, DP590-HR is the more ductile: elongation 22% versus 18% for DP590-BH.
DP590-BHChoose it when strength drives the design.
DP590-HRChoose it when the part is bent, formed or impact-loaded.
DP590-BH vs DP590-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.

DP590-BH vs DP590-HR — frequently asked
Is DP590-BH stronger than DP590-HR?
Yes. DP590-BH has a typical yield strength of 460 MPa (66.7 ksi) against 400 MPa (58 ksi) for DP590-HR — about 15% more. Tensile strength is 660 MPa (95.7 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, BH or HR?
CR is the default DP590 condition in the FabDigit quote flow (neither BH nor HR). 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 DP590-BH over DP590-HR?
Pick DP590-BH when strength drives the design. Pick DP590-HR when the part is bent, formed or impact-loaded.
