Abstract: A method and an apparatus for selecting at least one steel grade from a stock of data, stored in a memory, for a population of a plurality of steel grades using a data processing device, wherein the method has the following steps: (a) a selection device (11) which can be operated by a user is displayed on a display means (12) which can be used to set values for at least two steel grade features which respectively denote the steel grades; (b) the stock of data is queried for a steel grade for which the stock of data stores values for steel grade features which correspond to the set values of the steel grade features or which fulfil conditions which are dependent on the set values, and (c) if said query is satisfied by a steel grade and possibly in so far as said steel grade fulfils one or more further conditions, said steel grade or information representing it is displayed on the display means (12).
