Material from E215,E235,E355,St 37.4 St 35 E235,E355 etc.

Delivery condition: NBK

Length:3-6m

Packaging: In wooden boxes package.

BK means that the tubes do not undergo heat treatment

BKW means the final heat treatment is followed by cold drawing involving limited deformation

Appropriate further processing allows a certain degree of cold forming

BKS means Heat treatment is applied following the last cold forming process

GBK means the last cold forming process is followed by annealing

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