Mandrel is one of the key instruments to manufacture seamless steel tubes. Our company is capable of producing a series of mandrel, such as MPM, PQF, FQM, with the diameter ofΦ80-450mm, the length of 2500-17500mm, as a result of making the best use of our advantage in steel making, forging, heat treatment, machining plating chromium adequately. The raw steel material is AISI H13 or 4CrMoSiV1, based on enterprise specifications.
