STEEL FOR WELDED PIPES
           

 

 

Applications

Based in their mechanical characteristics, these steels are suitable especially for the production of welded pipes. These steels have standard weldability for structural and enhanced weldability for high stremgth low alloyed steels and come with trimmed or mill edges.


Grades

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