Abstract
Method of manufacturing a product (1, 15) from steel, in which a steel with a metastable first phase in which the steel has first properties is manufactured and, by mechanical influences, is transformed into a second, thermodynamically more stable phase with second properties which are at least partly different from the first properties, and, for adapting the product to particular applications, the product (1, 15) is manufactured locally differently by modification with regard to said phases with different properties. A product according to the invention therefore has, over its surface and/or its thickness, at least two differently adapted areas (10, 11) with different properties of the steel.
