Beschreibung
Zusammenfassung:	In this steel plate the cleanliness of the metal structure is no greater than 0.08% the degree of segregation (a) 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.
