Cold-drawn steel pipe is a kind of cold-drawn seamless steel pipe with high precision and brightness produced by cold-drawn or cold-rolled process. Its inner and outer diameters can be precise to less than 0.2mm. When bending and torsion strength are the same, the weight is lighter, so it is widely used in manufacturing precision mechanical parts and engineering structures. It is also often used in the production of conventional weapons, barrels, shells and so on.
Commonly used materials are 10 #, 20 #, 35 #, 45 #, 20cr, 40Cr, 20CrMo, 16mn, 27simn, 304, 201, 310s, high quality carbon structural steel. 标准：
Used for manufacturing mechanical structure, hydraulic equipment, automotive parts, steel sleeve.
1. The outer diameter is smaller.
2. High precision can be used for small batch production.
3. Cold-drawn products have high precision and good surface quality.
4. The transverse area of steel tube is more complex.
5. Steel pipe has better performance and denser metal.
