STEEL FOR AUTOMOTIVE INDUSTRY

Prázdny

In category Cold Rolled Steel

Prázdny

 

 

CHARACTERISTICS

Steels for the automotive industry are suitable for cold forming. They exhibit high mechanical resistance due to solid solution hardening with phosphorus. Because of their good impact and fatigue resistance they are used for pressing parts of automotive bodies and for automotive structural components.

product forms

Coils

wide strips with a rolled width of 600 mm and more, supplied in coils

Strips

cut from wide strips, width less than 600 mm, supplied in coils

Sheets

sheets cut from wide strips supplied in sheets

APPLICATION

Due to their good impact and fatigue resistance, they are used for body mouldings and for car structural components.

HC220P, HC260P according to EN 10268:2006

and in the corresponding grades according to international (ISO) or national technical standards (DIN, JIS, ASTM, ....)
