Pipe and Tube Specifications
This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified

Description
|
|
Cold finished (hard)
|
BK
|
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.
|
|
Cold finished (soft)
|
BKW
|
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
|
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
|
The last cold forming process is followed by annealing in a controlled atmosphere.
|
|
Normalized
|
NBK
|
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
