The successful use of P/M methods for the production of sensor rings used in antilock brake systems is predicated upon the attainment of a combination of mechanical, magnetic, and corrosion resistance properties. This paper summarizes these properties for high temperature vacuum and hydrogen sintering in commercial furnaces. Properties are also compared with parts sintered at lower temperatures and the effects of repressing and annealing are included. The results are analyzed with respect to microstructure and chemical analysis.
