United Heavy Machinery Plants is one of the world's leading manufacturers (along with JAPAN STEEL WORKS, CHINA FIRST HEAVY INDUSTRIES and CHINA ERZHONG) of large and extra-large items made from special steels that are used for traditional power and nuclear power, metallurgical and petrochemical machine-building, as well as special-purpose items.
The important competitive advantages of United Heavy Machinery Plants include its own metallurgical complex, its diversity of various-weight and various-dimensioned products made from a wide range of special steels, and the convenient geographic distribution of its production capacities.
This business line is represented by OMZ-SPECIAL STEELS, OMZ-FOUNDRY, and URAL METALLURGICAL PLANT.
OMZ-Special Steels is the largest Russian manufacturer of semifinished metallurgical products made from special steel used for nuclear power, petrochemical machine-building, and other branches of industry.
The backbone of OMZ-Special Steels' production capacities is its unique, superpowerful latest-generation steelmaking complex DSP-120 with a capacity of more than 250 thousand tons per year.
The high quality of its steel is guaranteed by the employment of secondary refinement in purification and vacuum units, as well as by the use of electroslag- and vacuum-arc remelting.
Pieces are forged on four hydraulic presses, including on one of Europe's largest automated forging plants with a force of 12,000 tf.
Metallurgical pieces are manufactured in accordance with GOST standards, OST standards, technical specifications, the standards of JIS, ASTM, NFA, BS, and DIN, and other specifications and technical requirements of the customer.
