Abstract
Although conventional free-cutting soft-magnetic stainless steel contains Pb to facilitate machining, the replacement and elimination of Pb is required from the standpoint of environmental protection. In this article, the authors report the development of new Pb-free machinable soft-magnetic stainless steels in which titanium carbo-sulfide is used as an inclusion. The microstructural evolution, magnetic properties, corrosion resistance, machinability and mechanical properties of these new free-cutting stainless steels are presented.
