Annealed DOM Drawn Over Mandrel Tubing , Automotive SAE J525 Tubing

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 r

esult 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 normailzed 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 dimesions ( OD, ID, or wall)
Unless otherwise agreed upon between customer and us., dimensional tolerances shall apply to the tube OD and wall dimensions.
