Abstract (en)
[origin: ES8405079A1] A work-hardenable austenitic manganese steel has a base composition (each in percent by weight) of 0.7 to 1.7 carbon, 5.0 to 18.0 manganese, 0 to 3.0 chromium, 0 to 4.0 nickel, 0 to 2.5 molybdenum, 0.1 to 0.9 silicon, up to 0.1 phosphorus and contains micro-alloying elements of 0.0 to 0.05 titanium, 0.0 to 0.05 zirconium and 0.0 to 0.05 vanadium the remainder being iron and impurities arising from the melting process. The ratio of carbon to manganese is in the range of 1:4 to 1:14 and the total amount of micro-alloying elements is limited to a range of 0.002 to 0.05 percent by weight. The melt of the base composition is tapped at 1,450 DEG C. to 1,600 DEG C. into a casting ladle in which the micro-alloying elements are added. An ingot is cast, cooled, reheated to austenitization temperatures and quenched.
