Steel DP1180-BH vs DP1180-CR

Steel · DP1180 temper comparison

DP1180-BH and DP1180-CR are two conditions of the same steel grade, DP1180: BH (after paint-bake) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. DP1180-BH is the stronger of the two: yield strength 1,080 MPa (157 ksi) against 950 MPa (138 ksi) for DP1180-CR, about 14% more. In exchange, DP1180-CR is the more ductile: elongation 7% versus 5% for DP1180-BH.
