PROCESS FOR MANUFACTURING HIGH MANGANASE CONTENT STEEL WITH HIGH MECHANICAL RESISTANCE AND FORMABILITY, AND STEEL SO OBTAINABLE |
摘要 |
The subject of the present invention is a process for the production of an austenitic steel with high mechanical resistance and formability. The proposed steel has the following chemical composition in percentage by weight: C 0.2-1.5; Mn 10-25; optionally Ni<2; 0.05-2.00; A1 0.01-2.0; N<0.1; P+Sn+Sb+As<0.2; S+Se+Te<0.5; and optionally Nb+Co<1 and/or Re+W<1, the balance being Fe apart from unavoidable impurities, and is subjected to a specific recrystallization annealing treatment. Another subject of the present invention is the so ob- tainable austenitic steel product and the use thereof in the automotive industry. Figure 2 shows the microstructure - of a TWIP steel according to the invention after deformation - wherein the geminates presence is observed. |
