Drawn Over Mandrel Steel Tube SAE J525 ERW Cold Drawn Seamless Tube Annealed

Drawn Over Mandrel Steel Tube SAE J525 ERW Cold Drawn Seamless Tube Annealed

Quick Detail:

SAE J525 Welded Cold Draw Low Carbon Steel Tubing annealed for bending and flaring
 

Size range: O.D.:30-350mm     W.T.:1-15mm      L: 12000mm or Cut to Short Pieces as specified length

Applications:  for Bending and Flaring, Auto Parts

Manufacture:

The tubing is made from flat-rolled steel shaped into a tubular form, the edges of which are joined and fused together by electric-resistance welding. After forming and welding, the tubing is normalized and subject to a cold-drawing operation that shall result in a 15% minimum reduction in cross-sectional are, of which 8% shall consist in a reduction in wall thickness. Sequent to cold working, the tubing shall be normaIized via an atmospherically controlled method to produce a finished product that will meet all requirement of SAJ525

Dimensions and Tolerances:

The tolerances applicable to the tubing outside diameter and inside diameter are shown in Table 1.

The tolerances applicable to the tubing wall thickness are shown in Table 2

Dimensional tolerances can only apply to two of the three tubing dimensions ( OD, ID, or wall)

Unless otherwise agreed upon between customer and us., dimensional tolerances shall apply to the tube OD and wall dimensions.
