Abstract
In a process for producing hot rolled steel strip with adjusted strength a steel with 0.04 to 0.06% carbon, at most 1% silicon, at most 1% manganese, 13 to 18% chromium, at most 2% nickel, balance carbide formers and iron, inclusive of impurities due to melting, is melted, the actual content of carbide formers within the specified limits is determined, a rolling oversize for a subsequent hot rolling is established in dependence on the actual content of carbide formers, and the hot rolled strip is solution annealed at a temperature of 920.degree. to 1050.degree. C. and quenched to a ferritic-martensitic structure and cold rolled down to the specified final thickness.
