Abstract:
A method for producing an automobile column is disclosed. The automobile column has a region of a first type and a region of a second type which have mutually different strengths. A transition region having a width of less than 50 mm is formed between the two regions. The automobile column has in the region of the first type a bainitic structure and in the region of the second type a martensitic structure.
