Феррохром ФХ100 ГОСТ 4757-91

<b>Феррохром </b>— это такой сплав железа и хрома (около 60 %), применяется для легирования стали и сплавов. Основные известные примеси — углерод (до ~5 %), кремний (до 8 %), сера (до 0,05 %), фосфор (до 0,05 %). Получают при восстановлении достаточно богатых (с высоким содержанием оксида хрома и высоким отношением оксид хрома/оксид железа) хромитовых руд (или концентратов) углеродистым восстановителем (обычно кокс).
