Résumé

The normalizing of ferritic-pearlitic steels is a heat treatment, which consist of reheating into the austenite and subsequent air-cooling. For greater thickness, e.g. 100 mm, variations in the requirements may be permitted or required for particular applications but a reduction of the required impact energy is not allowed. The most important cote of the cost can be eliminated if the process normalizing rolling is applied.
