Chrome Core® alloys are a family of controlled chemistry, ferritic 8 and 12% chromium-iron alloys which are candidates for use in magnetic components where corrosion resistance superior to that of pure iron, low carbon steel and silicon-iron alloys is desired without the substantial decrease in saturation induction associated with the 18% Cr ferritic stainless steels.
Applications could include electro-mechanical devices requiring some degree of corrosion resistance, either in service or for extended shelf life without the need for protective coatings. Chrome Core alloys have been considered for use in automotive components such as fuel injectors, fuel pump motor laminations and ABS solenoids. Each chrome level is available in both a standard and a free-machining grade.
