U. S. Steel Kosice

What U. S. Steel Kosice does

U. S. Steel Košice, s.r.o. (USSK) is the largest integrated steel producer in Central Europe, operating a blast furnace–based metallurgical plant in Košice, Slovak Republic, with an annual production capacity of 4.5 million tons and approximately 8,000–9,000 employees. The company manufactures a full portfolio of flat and long steel products — hot rolled, cold rolled, hot dip galvanized, organic coated, tin plate, electrical steel, and spiral welded pipes — supplemented by by-products such as blast furnace slag, fly ash, and coke tar, and supported by in-house logistics, R&D, customer technical service, and testing laboratories (Labortest).

USSK serves five primary industrial verticals: automotive, packaging, construction, appliance, and energy. Its go-to-market is B2B enterprise direct sales augmented by steel service centers, a non-prime e-commerce portal, and in-house transport/logistics. Pricing is quote-based and not publicly disclosed. Customers benefit from grade qualification support, technical service, and a broad product portfolio covering high-strength, formable, and specialty steel grades.

Following Nippon Steel Corporation's 2024–2025 acquisition of United States Steel Corporation (announced December 2023 for ~$14.9B enterprise value), USSK transitioned to direct Nippon Steel ownership in 2026 and is positioned as a core European operating hub within Nippon Steel's global strategy. The company is ISO 9001 and ISO 14001 certified, GDPR/CCPA compliant, and committed to decarbonization under a 2022 Memorandum of Understanding with the City of Košice. SAP ERP modernization (Quality Award 2025) and the Data Studio analytics platform represent its principal digital initiatives.
