EN10305-2 E275 WT0.5 High Precision Welded Steel Tube Welding Round
Tubing For Machine
Description:
High-precision welded steel tube round tubing for demanding machine
applications. Made from high-quality steel alloys, our tubes are
precision-manufactured to ensure exceptional strength, accuracy and
durability. With tight tolerances and smooth finishes, our round
tubing is ideal for hydraulic lines, pneumatic lines, and machinery
components, providing reliable performance in high-stress
environments.
| Material: | E275 |
| Other Material Aviable | 45#, E235, E355 |
| Standard: | EN10305-2 |
| Delivery Condition: | +C,+N |
| Size Range: | Outer Diameter:φ10-φ50
Wall Thickness: 1.5-8 |
| Application: | High Precision Steel Tube is Widely Used in Automotive Part,
Hydraulic System, High-precsion Machining. |
Produced by cold drawing over mandrel and die on the ERW welded
steel tube, to achieve better tolerance and good concentricity,
both outside and inside weld seam is completely removed during the
cold drawing process.
