Product Description

TORICH EN10210-1 Hot Finished Heavy Wall Steel Tubing for General Engineering Purpose

Standard	EN10210-1 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
Application	For Construction & Decoration, For General Engineering Purposes
Manufacture	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 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 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.
