Abstract

A ferrite-type hot-rolled stainless steel sheet is composed of a selected class of elements in specified amounts. Even when cold rolling and its subsequent process steps are omitted, the hot-rolled steel sheet is sufficiently workable and excellent in surface roughening resistance and high-temperature fatigue properties after working. The steel sheet is easy to produce with a wide range of annealing temperatures.
