Development of an Import-Replacing Technology Aimed at Manufacturing Mandrels Маde of X35CrMoV05KU-UNI 2955 Steel for Tubular Mills

详细

The “Kurchatov Institute” NRC, “Prometei” CRI of Structural Materials, in collaboration with the “OMZ-Spetsstal’” developed and mastered the technology for manufacturing long mandrels made of X35CrMoV05KU-UNI 2955 steel with guaranteed service life. The obtained mandrels meet the requirements of technical documentation as for their mechanical properties, hardness, grain sizes, ultrasonic testing, and contents of nonmetallic impurities. These mandrels passed through the industrial tests at the Taganrog Pipe Plant. The service life of the mandrels produced at the “OMZ-Spetsstal’” corresponds to the foreign analogs.
