EN 10305 Seamless cold drawn precision steel tubes for mechanical applications and for hydraulic and pneumatic power systems.

Typical fields of application are in the automotive, furniture and general engineering industries.

Steel tubes for precision applications-Technical delivery conditions-Part 1: Seamless cold drawn tubes.

Seamless Precision Steel Tubes according to EN 10305-1

Standard and Steel grade:

EN10305-1 E215
EN10305-1 E235
EN10305-1 E355

Feature:

High precision and high brightness, the inner and outer surface of the tubes have high cleanness without oxid mechanical properties of the final tubes also come out excellent promising no leakage under high pressure no deformation after cold-bent and no cracks when flaring and flattening ensuring the efficient operation in all service.

Quality grade

The tubes are supplied in the following quality grades :

A) precision steel tubes intended primarily for mechanical stressing, without any particular quality requirement and without acceptance test certificate.
B) precision steel tubes intended primarily for mechanical stressing, with special quirement and exclusively with acceptance test certificate.
C) precision steel tubes with special requirement according to section 12. Theses requirements and corresponding tests must be agreed, with the customer having to specify his requirements at the time of enquiry and on ordering.

Condition on delivery:

Term	Symbol	Explanation
Cold-finished/hard (cold-finished as-drawn)	BK	No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft (lightly cold-worked)	BKW	After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed	GBK	After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized	NBK	The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
