Precision Steel Tube: A precision steel tube is a hollow steel cylinder manufactured with high dimensional accuracy, tight tolerances, and excellent surface quality. These tubes are used where exact fit, performance, and strength are critical, such as in hydraulic systems, automotive, and aerospace industries.
Key Characteristics:
Typical Applications:
Applicable Standards: ASTM A519 / EN10305-1 / DIN 2391 / GB3639.
Precision seamless steel tubes are manufactured without welds for applications requiring extreme strength. Produced from solid steel billets, they are cold-drawn to achieve tight tolerances and smooth surfaces.
Applicable Standards: EN10305-2 / ASTM A513 Type 5 & 6 / DIN 2393.
Precision welded tubes are formed from flat steel strips and welded. They offer high dimensional accuracy and are ideal for shock absorbers, steering columns, and drive shafts.
We provide one-stop steel tube processing services, including honing, bending, and CNC machining. After processing, straightness can reach 0.05mm, ideal for motor shafts and rollers.
