This article translates American F-M company to our country’s bearing and the GCr15 steel appraisal of the quality appraisal, the bearing manufacture quality conforms to the request, the Daye steel vacuum degassing refining GCr15 steel oxygen content achieves the international high quality steel level, on the steel five Plant steel is also close to high quality steel. GCr15 steel D-clamps at both mills also reached international high standards. F-M Company recognizes the metallurgical quality of vacuum degassing refined GCr15 steel at Daye Steel and No. 5 Steel Works, agreeing to manufacture bearings for export to the U.S. market.
