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 %.
