Abstract (en)
[origin: EP2759614A1] A molten steel containing 1.2-7 wt.% silicon, 0.4-4 wt.% boron, 0.5-4 wt.% carbon and 1.5-8 wt.% phosphorus, optionally containing 5 wt.% or less copper, 10 wt.% or less chromium, 10 wt.% or less aluminum, 0.5 wt.% or less nitrogen, 2 wt.% or less niobium, 3 wt.% or less manganese, 2 wt.% or less titanium, 2 wt.% or less vanadium, and remainder of iron and unavoidable impurities is cast in a casting device (2). The obtained cast strip (B) is cooled, to obtain a flat steel product having an amorphous, partially amorphous or fine crystalline structure. A molten steel containing 1.2-7 wt.% silicon, 0.4-4 wt.% boron, 0.5-4 wt.% carbon and 1.5-8 wt.% phosphorus, optionally containing 5 wt.% or less copper, 10 wt.% or less chromium, 10 wt.% or less aluminum, 0.5 wt.% or less nitrogen, 2 wt.% or less niobium, 3 wt.% or less manganese, 2 wt.% or less titanium, 2 wt.% or less vanadium, and remainder of iron and unavoidable impurities is cast in a casting device (2). The obtained cast strip (B) is cooled, to obtain a flat steel product having an amorphous, partially amorphous or fine crystalline structure. The particle size of fine crystalline microstructure is 10-10000 nm.
