DIN EN 10210-1 Hot finished structural hollow sections of non-alloy and fine grain steels
 
 
DIN EN 10210-1
Hot finished structural hollow sections of non-alloy and fine grain steels
Part 1:  Technical delivery conditions
Part 2:  Tolerances, dimensions and sectional properties
 
Cold forming:
Process is done at ambient temperature
 
Structural hollow section manufacturing process:
Structural hollow sections are manufactured by seamless or by welding.
Welded sections manufactured by continuous process.
Electric welded hollow sections are supplied without trimming the internal weld bead.
 
Delivery condition:
Qualities  JR, J0, J2 and K2 - Hot finished
Qualities  N and NL - normalized.  (normalized rolled)
- for accelerated cooling    +DC
- for quenching and tempering    +QT
 
Surface condition:
The hollow sections have a smooth surface corresponding to the manufacturing method used; bumps, cavities or shallow longitudinal grooves resulting from the manufacturing process are permissible, provided the thickness is within tolerance.
 
End:  Square cut
