Russian steel maker United Metallurgical Company, the largest Russian manufacturer of solid-rolled railway wheels for all types of rolling stock, for the second year in a row was ranked among the best suppliers of Siemens Mobility, a leader in transport solutions. OMK has been cooperating with Siemens Mobility since 2016, supplying high-tech wheels for the Lastochka high-speed passenger electric train designed for operation at speeds up to 160 km / h. In the outgoing year, the partners completed the procedure for serial production of wheels for Lastochka; previously, OMK could supply only pilot batches of limited volume. In 2021, the company shipped over 1,800 of these wheels to Siemens Mobility. In addition, specialists from Siemens Mobility began controlled operation of OMK wheels for the Sapsan high-speed electric train, which has a design speed of up to 250 km / h. Following the results of controlled operation, which will end in mid-2022, the parties will discuss industrial supplies of wheels for Sapsan.All products are manufactured at the Vyksa plant of OMK in the Nizhny Novgorod Region, which is the only manufacturer of wheels for high-speed and high-speed traffic in Russia. OMK employees took part in the development of technical specifications for the supply of wheels for the Lastochka and Sapsana electric trains, taking into account the requirements of both Russian and foreign standards.Unlike serial wheels, wheels for high-speed and high-speed movement are extremely demanding in terms of geometry and steel quality. This year, the OMK plant in the Nizhny Novgorod Region carried out warranty tests and put into pilot operation a line for applying a protective coating to the surface of railway wheels for high-speed rolling stock. Now OMK is preparing for the qualification of the process of painting wheels for "Swallow" and "Sapsan".
