제품 설명
Annealed DOM Drawn Over Mandrel Tubing SAE J525 Automotive Steel Tubes
Annealed DOM Drawn Over Mandrel Tubing, SAE J525 Automotive Steel Tubes
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 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.
E155,E195,E235,E275,E355, other materials upon agreement with customers.

3. Production method:
Cold drawn on the welded steel tubes, to reach high accuracy on the OD and WT tolerance
4. Packing:
In Hexagonal Bundles, with anti-rust oil protection, with seaworthy packing
5. Deliver condition:
1). +C No heat treatment after the final cold drawing 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
Production Steel Tube:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking.
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
