Abstract

Fe-Cr based soft magnetic alloys have high corrosion resistance and magnetic property. Therefore they are widely used for the solenoid valves and electronic devices. In this situation, economic Fe-Cr based soft magnetic alloy, which has excellent soft magnetic properties and practical corrosion resistance is required. SUS430 is one of the candidate alloy with soft magnetic property in stainless steels. To achieve the economic aim, sintering process is useful to make low Cr alloy by adding the pure iron powder to SUS430 powder. While, reduction of Cr content deteriorate corrosion resistance. Sintered SUS430 based alloys with different Cr content were prepared using metal injection molding process. We carried out slow strain rate tensile (SSRT) test and open circuit potential (OCP) to evaluate their mechanical properties and electrochemical properties.
