DIN EN 10210-1 Hot finished Heavy Wall Steel Tubing 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
Structrual hollow section manufacturing process:
Structural hollow sections are manufactured by seamless or by welding.
Welded sections manufactured by contiuous process.
Electric welded hollow sections are supplied without trimming the internal weld bead.
Delivery conditon:
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 conditon:
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
