Brief description:

Description Name:Introduction EN 10210-1 hot-finished hollow section tube is made from non-alloy structure steel and fine-grain structure steel. It features simple form, excellent strength properties, durable, compact structure and wide specifications and dimensions. Adopting appropriate types of steels can optimize function and affordability of this hollow section pipe. This hollow section tube is broadly made use of in the frame structure of buildings, bridge structure, railing, mechanical frame structure, frame structure of transport vehicle, scaffolding, rack or spline and pinion elevator,

The tubes shall be supplied in one of the delivery conditions as follows:

Designation	Description
Annealing	The purpose of annealing is to remove the internal stress generated during hot working, so that the microstructure of the metal is homogenized (to obtain approximately balanced microstructure), and improve mechanical properties
Normalizing	Normalizing is a special form of annealing, because its cooling rate is faster than annealing, it can get finer grains and uniform organization, so that the strength and hardness of the metal have been improved, and it has better comprehensive mechanical properties.
Tempering	The purpose of tempering treatment is to reduce the brittleness caused by quenching treatment and eliminate internal stress, stabilize the geometric size of metal parts and obtain the required mechanical properties.
Quenching	Improve the strength, hardness and wear resistance of the metal
