<p>In this steel plate, the cleanliness of the metal structure is no greater than 0.08%, the degree of segregation (α) of Mn is no greater than 1.6, and during hot forming, the post-hot-forming average hardness difference (ΔHv) between a low-strain formed section that has incurred a plastic strain of no greater than 5% and a high-strain formed section that has incurred a plastic strain of at least 20% is no greater than 40.</p> |
