High corrosion resistant ferritic stainless steel JFE443CT has been developed. With the increase of Crcontent to 21% and the addition of Cu, its corrosion resistance is equivalent to that of SUS304 in the neutral chloride environment. Moreover, without the addition of Ni and Mo, its price is stable even when the price of Ni and Mo soars. JFE443CT has been applied widely as the substitution for SUS304, the price of which is fluctuating severely.
