Product Overview

Standard EN10305-2 Material E255 High Precision Welded Steel Tube is an excellent choice for multistage hydraulic cylinder applications. This cold drawn welded pipe utilizes precision resistance welding (ERW) and cold drawing processes to manufacture steel tubes that meet the EN 10305-2 European mechanical cold drawn steel tube welding standard.

Technical Specifications
Material E255
Standard EN10305-2
Delivery Condition +C, +LC, +SR, +N, +A
Size Range Outer Diameter: φ6-φ80
Wall Thickness: 0.5-10
Application High Precision Steel Tube is Widely Used in Automotive Parts, Hydraulic Systems, High-precision Machining
Delivery Condition Definitions
  • +C: No heat treatment after the final cold drawing process
  • +LC: After the final heat treatment there is a suitable drawing pass
  • +SR: After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
  • +A: After the final cold drawing process the tubes are annealed in a controlled atmosphere
  • +N: After the final cold drawing operation the tubes are normalized in a controlled atmosphere
Manufacturing Process

Produced by cold drawing over mandrel and die on the ERW welded steel tube, achieving superior tolerance and excellent concentricity. Both outside and inside weld seams are completely removed during the cold drawing process.
