Process for the production of stove-finished structural components from ageing-sensitive steel

   
   

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.sup.2. The characterising feature of the invention is that the cold strip is converted by dressing into a yield point stretch-free state (R.sub.eh -R.sub.el <2 N/mm.sup.2), 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.

L'invenzione riguarda i procedimenti per la produzione di un elemento della struttura stufa-rifinito inarc-resistente dall'acciaio non-invecchiantesi laminato a freddo e vestito della striscia (striscia fredda) con alto potenziale d'indurimento, specialmente di più di 70 N/mm.sup.2. La caratteristica caratterizzante dell'invenzione è che la striscia fredda è convertita vestendosi in limite di snervamento allung-libero dichiara (R.sub.eh - R.sub.el
