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 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)
  (+LC)  
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.

Quality Assurance

1. Strict according to DIN2391/EN10305 or other standard.

2. Sample: Sample is free for test.

3. Tests: Salt spray test/Tensile test / Eddy current / Chemical composition test according to customers’ request

4.Certificate: IATF16949, ISO9001, SGS etc.
