Abstract

A hot-rolled austenitic manganese steel strip having a chemical composition in percent by weight of 0.4% = C = 1.2%, 12.0% = Mn = 25.0%, P = 0.01% and Al = 0.05% has a product of elongation at break in % and tensile strength in MPa of above 65 000 MPa%, in particular above 70 000 MPa%. A cold-rolled austenitic manganese steel strip having the same chemical composition achieves a product of elongation at break in % and tensile strength in MPa of above 75 000 MPa%, in particular above 80 000 MPa%.
