Abstract

PURPOSE: To obtain a heat resistant ferritic stainless steel with superior press formability usable for a car converter, a burner, etc. by hot rolling a steel contg. a specific amt. of Cr, Si, Mn, C, N and Zr, followed by annealing, cold rolling and annealing.
CONSTITUTION: A steel consisting of Cr; 11.0W20.0%, Si≤1.5%, Mn≤1.5%, C+N; 0.02W0.06%, Zr; 0.2W0.6% [Zr%=10(C%+N%)±0.15%] and the balance Fe essentially is hot rolled and annealed at 770W1000°C. In case the hot rolled sheet is batch-wise annealed as a coil, the coil is held at a predetermined time for above several hr. When the sheet is fed to a continuous annealing furnace while uncoiling or the sheet is annealed in a batch-wise furnace, the annealing is carried out in a short time. The annealed sheet is then cold rolled and annealed again at 700W1000°C to obtain a heat resistant ferritic stainless steel with superior press formability.
