DRAWING STEELS
           

 

 

Applications


Low carbon steel sheets (deep drawing) are suitable for deep-drawing and cold forming. The sheets are weldable; higher grades are suitable for surface treatment by hot dipping, enameling or other coating methods.

U. S. Steel Košice has implemented and maintains a quality control system in accordance with the standard EN ISO 9001, as well as in accordance with ISO/TS 16949 for automotive industry, issued by TÜV SÜD. A part of production is certified in accordance with the European Parliament Regulation 97/23/EC, AD2000W1.


Grades

The hot rolled products are classified into quality grades according to chemical composition and mechanic properties.
