Molybdenum Mandrel

Our company is the noteworthy names engaged in manufacturing, exporting and supplying a wide range of Molybdenum Mandrel in Zhengzhou, Henan, China. The high temperature molybdenum mandrels have been developed by our company and the materials science & engineer Institute of Zhengzhou University. The R&D crafts include selecting and mixing raw materials which are compressed into embryos material, sintering in the intermediate frequency furnace in 850-1950a and then turning and molding. The average density of the products is more than 9.7g/cm3. Compared with the common molybdenum mandrels , the density improves 2-6%, the Vickers hardness reaches above 350kg/mm2 and the abrasion resistance increases 60-80%. Mainly used for piercing seamless tube, such as stainless steel tubes, alloy steel tubes , high-temperature alloy tubes.
