Abstract

Manganese-boron-steel (I) comprises (in wt.%): carbon (0.1-0.2); silicon (0.05-0.3), manganese (0.8-1.8), nickel (0.5-.8); phosphorus (= 0.015), sulfur (= 0.003), boron (0.0002-0.008), optionally titanium (0.01-0.1), optionally aluminum (0.01-0.05), optionally nitrogen (0.002-0.005) and rest of iron and unavoidable impurities. Independent claims are included for: (1) a flat steel product comprising (I); and (2) a process for the preparation of the steel product comprising smelting a steel melt containing (I), pouring the melt to slabs or thin slabs, thermally-rolling the slabs or thin slabs at 850-900[deg]C to form a hot-rolled strip and hasping the hot-rolled strip at 560-600[deg]C.
