Abstract
The invention relates to processes for the production of a buckling-resistant stove-finished structural member from cold rolled and dressed strip (cold strip) non-ageing steel with high bake-hardening potential, more particularly of more than 70 N/mm . The characterising feature of the invention is that the cold strip is converted by dressing into a yield point stretch-free state (R −R <2 N/mm ), then stored at a temperature below room temperature and further processed into the form of a structural member, whereafter the strip is finally stove finished.
