Abstract
The present invention discloses zinc-modified ferritic stainless steels and a manufacturing method thereof. The chemical composition of the ferritic stainless steels comprises 14-16 wt % chromium, 0.001-4 wt % zinc, 0.001-0.02 wt % nitrogen, 0.003-0.015 wt % carbon and the remaining of weight percentage of the composition is iron. By adding zinc into the composition, the ferritic stainless steels of the present invention have stronger capacity of corrosion resistance and lower manufacturing cost, as compared to the conventional stainless steels.
