Cold-drawn Precision Seamless Steel Tube
Introduction:
Cold-drawn precision seamless steel tube is made through cold drawing process that creates a uniform, precision product with substantially improved tolerances, surface finish and tensile strength, increased hardness, and good machinability. Close dimensional accuracy is achieved through tight control of both outside and inside diameters.
Compared with hot rolled seamless steel tube, cold drawn seamless steel tube features higher strength, better extensibility, and higher abrasion resistance. It can be used for automobile shock absorber, drive shaft, steering system, airbag system, motorcycle front fork and so on.
