| description | The invention relates to a variably rolled steel strip, sheet or blank, having at least one portion having a high thickness and at least one portion having a low thickness, wherein the variation in thickness between the high thickness and the low thickness is at least 35%, and wherein in the portion with high thickness the yield strength is 350 MPa or higher and the tensile elongation A50 (in %) and sheet thickness t (in mm) satisfy the equation of A50 / t0.2 >= 14, and in the portion with low thickness the yield strength is 450 MPa or higher and the tensile elongation A50 (in %) and sheet thickness t (in mm) satisfy the equation A50 / t0.2 >= 17.
本发明涉及可变轧制的钢带材、片材或坯料，其具有至少一个具有高厚度的部分和至少一个具有低厚度的部分，其中在高厚度和低厚度之间的厚度变化为至少35％，并且其中在具有高厚度的部分中屈服强度为350MPa或更高且拉伸伸长率A50(以％计)和片材厚度t(以mm计)满足A50/t0.2≥14的等式，并且在具有低厚度的部分中屈服强度为450MPa或更高且拉伸伸长率A50(以％计)和片材厚度t(以mm计)满足A50/t0.2≥17的等式。 |
