E355 DOM High precision tubing DOM Steel Tubing for

telescopic cylinders Steel Tubes

Size Range: OD: 6-329mm, WT: 1-15mm, Length: 5.8m/6m, maximal 11.8m

Standard:EN10305-2 Welded Precision Steel tubes, is 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.

Materials:E355 full aluminum killed fine grain practice.

Process:Welded, cold Drawn-Over-Mandrel (DOM), Stress Relieve Annealed (SRA; BK+S), round precision tubing.

The welded tube must be full body normalised in case of stretch reduction after welding and prior to cold drawing.

Otherwise only weld seam normalised is accepted.

Delivery condition:

1). +C No heat treatment after the final cold drawig process

2). +LC After the final heat treatment there is a suitable drawing pass

3). +SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere

4). +A After the final cold drawing process the tubes are annealed in a controlled atmosphere
5). +N After the final cold drawing operation the tubes are normalized in a controlled atmosphere
