Specification

 

Designation

Symbol

Description

Cold finished (hard)

BK(+C)

Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation

Cold finished (Soft)

BKW
(+LC)

The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)

Cold finished and stress-relieved

BKS(+SR)

Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

Annealed

GBK(+A)

The last Cold forming process is followed by annealing in a controlled atmosphere.

Normalized

NBK(+N)

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

 

DIN 2391 Precision seamless steel tube 

 

This Standard applies to seamless precision steel tubes; and, in compliance with ISO/DIS 3304, those tube dimensions have een selectied from the range of manufactura le tu e dimensions which are mainly used as design elements

If tubes having the tolerances and are produced according to the technical conditions of deivery as specified in this Standard are to e used as pipelines, then the dimensions specified in DIN 2448 may from time to time be used. These tubes must be ordered according to quality grade C.
