Abstract
Production of a martensitic steel strip having a high carbon content comprises melting a steel, casting the melt in a casting gap formed between two rotating rollers to form a thin strip having a thickness of maximum 10 mm, and rapidly cooling at a cooling speed of at least 200 K/s. Production of a martensitic steel strip having a high carbon content comprises: melting a steel; casting the melt in a casting gap formed between two rotating rollers to form a thin strip having a thickness of maximum 10 mm; and rapidly cooling at a cooling speed of at least 200 K/s. The steel comprises (in wt.%): at least 0.15 carbon (C), 12.0-20.0 chromium (Cr), at most 1.0 silicon (Si), at most 2.0 manganese (Mn), at most 2.0 molybdenum (Mo), at most 1.0 nickel (Ni), at most 1.0 vanadium (V), at most 0.1 nitrogen (N), at most 0.1 titanium (Ti) and a balance of iron (Fe) and impurities.
