Abstract (en)
[origin: WO2017021459A1] The invention relates to a high-tensile manganese steel containing aluminium, said steel having the following chemical composition (in % by weight): C: 0.01 to < 0.3; Mn: 4 to < 10; Al: > 1 to 4; Si: 0.01 to 1; Cr: 0.1 to 4; Mo; 0.02 to 1; P: < 0.1; S: < 0.1; N: < 0.3; the remainder being iron with unavoidable elemental inclusions associated with steel, and with optional alloying of one or more of the following elements (in % by weight): V: 0.01 to 1; Nb: 0.01 to 1; Ti: 0.01 to 1; Sn: 0 to 0.5; Cu: 0.005 to 3; W: 0.03 to 3; Co: 0.05 to 3; Zr: 0.03 to 0.5 and Ca: 0.0005 to 0.1. Said steel has an excellent combination of strength-, strain- and deformation characteristics. The invention also relates to a method for producing a sheet-steel product from said steel and to a sheet-steel product produced according to this method.
