Remarks:
Cold Finished (Hard): Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold Finished (Soft): 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)
6) Product Application Industry
Application Field:
Mechanical processing, machinery manufacturing, automobile
7) Quality Control
A. Advanced Production Equipment
B. Skill-full and Qualfied Workers, Training and Testing before Working
C. Strictly Qualtity Control System
8) Packing & Shipping
