The invention discloses an easy-cutting ferritic stainless steel relating to the easy-cutting ferritic stainless steel material used for making electromagnetic valve, etc., wherein, the chemical composition weight percent of the steel is as follows: less than or equal to 0.03 percent of C, 1.0 percent to 1.5 percent of Si, 0.6 percent to 1.0 percent of Mn, 0.15 percent to 0.30 percent of S, less than or equal to 0.04 percent of P, 16.5 percent to 18.0 percent of Cr, 0.75 percent to 1.25 percent of Mo, 0.20 percent to 0.50 percent of Ti and the rest, Fe and other inevitable impurities. Through reasonable improvement in composition proportion, the invention ensures that the ferritic stainless steel has excellent machinability, ferromagnetism and weldability and can meet the requirements of performances such as corrosion resistance, coercive force, magnetic induction and salt spray corrosion, thereby according with the requirements of electromagnetic valve manufacturers.
