Heat Treatment/ Delivery Condition	1.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 2.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) 3.Cold finished and stress-relieved annealing 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. 4.Annealed GBK(+A) The last Cold forming process is followed by annealing in a controlled atmosphere. 5.Normalized NBK(+N) The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
Delivery Time	45 days
Payment Term	30% TT in advance, Balance to be paid before shipment
Usage/Application	Truck drag link, automotive parts
