Title: FERRITIC STAINLESS STEEL AND PROCESS FOR PRODUCING SAME
Abstract:
Provided is a ferritic stainless steel having excellent moldability and ridging resistance characteristics and also being capable of being produced with high productivity, as a result of having: a prescribed component composition; 5-50 vol% ferrite crystal grains relative to the overall composition, said ferrite crystal grains fulfilling either or both a C concentration of at least 2CC and an N concentration of at least 2CN; and a Vickers hardness of no more than 180. CC and CN are, respectively, the C and the N content in the steel (in percent by mass).
