Cold-drawn steel tubes are precision cold-drawn seamless tubes with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.
What are the classifications of cold-drawn tubes？
1. Carbon steel Cold-drawn seamless tubes
This cold-drawn carbon steel seamless tubes are made of SAE 1020 steel or ST52.3 steel, and the carbon structure is very stable. The acceptance of this kind of steel pipe is much stricter than that of other steel pipes, and it is generally used in fields that have strict requirements on the flexibility of the steel pipe. Carbon steel cold drawn seamless tubing usually can be produced to honed tubing, which is widely used as hydraulic cylinder tubes for hydraulic cylinder barrel.
2. Small diameter seamless steel tubing
Small-diameter seamless steel pipes, for most people, they may not know that cold-drawn steel pipes can also be made into small-diameter steel pipes. In fact, the steel pipes of this material have low carbon content and considerable rigidity.
3. Precision seamless cold drawn steel tubes
This kind of steel tubes is mainly used for some mechanical structures that require precision, especially for some hydraulic equipment, which can play a significant role. Usually precision seamless cold drawn steel tubes are manufacctured as per DIN 2391 or EN 10305, they are widely used as hydraulic tubes.
Cold drawn steel tubes classifications by materials
- ST52 cold drawn steel tubes
- SAE 1020 cold drawn steel tubes
- CK45 cold drawn seamless steel tubes
- SAE 4140 cold drawn steel tubes: this type of CDS tubes are mostly used to produce 4140 hydraulic cylinder barrels.
- 27SiMn cold drawn seamles steel tubes.
