A natoly Sedykh is a Russian industrialist who is the founder and chairman of the United Metallurgical Company (OMK), one of Russia's largest producers of pipes, railway wheels, and other steel products. An economist by training, Sedykh began his career in the 1990s as a metals trader, capitalizing on the opportunities presented by Russia's transition to a market economy. He was a co-founder of the "Metallinvest" company which supplied raw materials to metallurgical plants.

In the late 1990s, Sedykh strategically acquired a controlling stake in the Vyksa Steel Works, a major pipe manufacturer, which became the cornerstone of his industrial empire. He consolidated this and other assets to form OMK. Under his leadership, the company has invested heavily in modernization and has become a key supplier to Russia's powerful oil and gas industry, which relies on OMK's large-diameter pipes for its pipelines. He has built his fortune by securing a dominant position in a critical niche of the Russian industrial sector.
