CA 2233117

In a process for producing a hardened stainless steel strip a steel containing 10 to 20% chromium, up to 3% nickel, up to 1.5% molybdenum, up to 1% manganese, up to 1% silicon, up to 0.6% titanium, up to 0.1% carbon and up to 0.1% nitrogen, balance iron and impurities arising from melting, is hot rolled and is then quenched directly from the rolling temperature. To adjust the strength the hot rolled strip may be cold rolled to its final thickness.

Dans un procédé pour produire un feuillard d'acier inoxydable trempé, un acier contenant de 10 à 20 % de chrome, jusqu'à 3 % de nickel, jusqu'à 1,5 % de molybdène, jusqu'à 1 % de manganèse, jusqu'à 1 % de silicium, jusqu'à 0,6 % de titane, jusqu'à 0,1 % de carbone et jusqu'à 0,1 % d'azote, le reste se composant de fer et d'impuretés résultant de la fusion, est laminé à chaud, puis trempé directement à partir de la température de laminage. Pour ajuster la résistance, on peut laminer à froid le feuillard laminé à chaud jusqu'à obtention de l'épaisseur finale.
