In this study. we have developed the manufacturing technology for high strength gray cast irons by using the spent permanent magnet scraps. The cast specimen inoculated by using a spent magnet scraps showed the excellent tensile strength up to 306MPa. This tensile strength value is 50MPa higher than that of the specimen cast without inoculation. https://safeersappliancers.shop/product-category/neff-u2acm7hn0b-n50-built-in-59cm-a-b-electric-double-oven-stainless-steel/
