Steel DP1470-BH vs DP1470-CR
Steel · DP1470 temper comparison
DP1470-BH and DP1470-CR are two conditions of the same steel grade, DP1470: BH (after 2 % prestrain + paint bake) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. DP1470-BH is the stronger of the two: yield strength 1,240 MPa (180 ksi) against 1,120 MPa (162 ksi) for DP1470-CR, about 11% more. In exchange, DP1470-CR is the more ductile: elongation 5.5% versus 3.5% for DP1470-BH.
DP1470-BHChoose it when strength drives the design.
DP1470-CRChoose it when the part is bent, formed or impact-loaded.
DP1470-BH vs DP1470-CR: 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.

DP1470-BH vs DP1470-CR — frequently asked
Is DP1470-BH stronger than DP1470-CR?
Yes. DP1470-BH has a typical yield strength of 1,240 MPa (180 ksi) against 1,120 MPa (162 ksi) for DP1470-CR — about 11% more. Tensile strength is 1,560 MPa (226 ksi) vs 1,520 MPa (220 ksi).
Which condition does FabDigit quote by default, BH or CR?
CR is the default DP1470 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 DP1470-BH over DP1470-CR?
Pick DP1470-BH when strength drives the design. Pick DP1470-CR when the part is bent, formed or impact-loaded.
