  • Drawing and cold rolling

Carbon steel grades for wire rod are classified in three families: low, medium and high carbon. The European standard EN 16120 for carbon grades defines a large range of grades with a carbon content from 0.03% to 1%.

Carbon content is the first parameter for obtaining the final mechanical properties defined by international standards (EN, ASTM, JIS,…). For a wider range of properties, alloying elements such as boron, titanium, vanadium or chromium can be added. 

The second parameter is strain hardening, induced by the drawing or rolling process. 

Specific customers’ requirements influence steel production standards to meet expected surface quality and ability for descaling or ultimate coating.

Key properties

  • Grade analysis
  • Microstructure homogeneity
  • Surface quality and descaling ability
