Steel DP980-CR vs DP980-HY

Steel · DP980 temper comparison

DP980-CR and DP980-HY are two conditions of the same steel grade, DP980: CR (cold rolled) versus HY (high-yield (Y700-class) DP980 variant). The chemistry is identical, so every difference below comes from the condition. DP980-HY is the stronger of the two: yield strength 780 MPa (113 ksi) against 680 MPa (98.6 ksi) for DP980-CR, about 15% more. In exchange, DP980-CR is the more ductile: elongation 9% versus 8% for DP980-HY.

DP980-CRChoose it when the part is bent, formed or impact-loaded.

DP980-HYChoose it when strength drives the design.

DP980-CR vs DP980-HY — frequently asked

Is DP980-HY stronger than DP980-CR?

Yes. DP980-HY has a typical yield strength of 780 MPa (113 ksi) against 680 MPa (98.6 ksi) for DP980-CR — about 15% more. Tensile strength is 1,050 MPa (152 ksi) vs 1,030 MPa (149 ksi).

Which condition does FabDigit quote by default, CR or HY?

CR is the default DP980 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 DP980-CR over DP980-HY?

Pick DP980-CR when the part is bent, formed or impact-loaded. Pick DP980-HY when strength drives the design.
