METHOD FOR MANUFACTURING ferritic STAINLESS STEEL WITH ENHANCED SURFACE QUALITY BY REDUCING ORANGE PEEL DEFECTS

摘要

PURPOSE: A method for manufacturing ferritic stainless steel is provided to obtain ferritic stainless steel with enhanced surface quality by controlling a grain size in an annealing furnace.;CONSTITUTION: A method for manufacturing ferritic stainless steel with enhanced surface quality is as follows. Cold rolled ferritic stainless steel is controlled in a temperature range of 1040-1060°C in a soaking zone(130) of a cold rolling and annealing furnace(145), thereby obtaining FGS(ferritic Grain Size Number) of 6-8. The ferritic stainless steel comprises Cr(Chromium) of 13.0-15.0wt.%, Si(Silicon) of 0.8-1.0wt.%, Nb(Niobium) of 0.2-0.4wt.%, Ti(Titanium) of 0.1-0.3wt.%, Fe(Iron), and impurities.;COPYRIGHT KIPO 2012
