New free-machining magnetic core stainless steel sheet containing 17% chromium was studied to develop. And the underwritten excellent properties were confirmed as well as good corrosion resistance, machinability and deep drawability.(1) After higher temperature (1200°C) annealing high magnetic properties were achieved as about 0.6 Oe in coercive force and about 6000 in maximum permeability. After proper cold rolling and subsequent annealing, the better magnetic properties were obtained.(2) The electrical resistivity was as high as 75μΩ·cm, and therefore good effective permeability was obtained.This material is suitable for application in alternating magnetic field.
