High Strength Low Alloy - U. S. Steel Košice, s.r.o

Application

Sheets from structural micro-alloyed steels with fine-grained structure and with guaranteed notch toughness at low temperatures are used for production of welded supporting structures, pressurized tanks, pipelines, for dynamic stressed chassis of transport equipment, wheel discs and profiles. Sheets are characterized by improved cold formability.
