  • Manganese steel strip having an increased phosphorous content and process for producing the same
    Patent number: 9677146
    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 %.
