<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a ferrite system stainless steel wire rod, bar steel, and steel tube excellent in cold workability and to provide a wire rod, bar steel, and steel tube manufactured by its method. SOLUTION: The method for manufacturing the ferrite system stainless steel wire rod, bar steel and steel tube excellent in cold workability and the wire rod, bar steel, and steel tube manufactured by its method capable of being obtained through further hot-rolling, using billet slant-rolled after bloom-rolling a large cross-section bloom or a steel bloom, and the wire rod, bar steel and steel tube manufactured by its method. And the method for manufacturing the ferrite system stainless steel wire rod, bar steel and steel tube excellent in cold workability characterized by the feature that in the above method, reduction of area at the time of bloom-rolling is 60% or more and reduction of area at the time of slant-rolling 40% or more, and the wire rod, bar steel and steel tube manufactured by the method.</p> |
