Main Characteristics
Controlled Small-Diameter Geometry: For a nominal outside diameter of 4.76 mm and a 0.50 mm wall, featuring nominal inside diameter of 3.76 mm and theoretical mass of approximately 52.5 g/m.
Formability: SAE J526 finished tubing features tensile strength of 290 MPa minimum, yield strength of 170 MPa minimum, and elongation over 50 mm of 14% minimum.
Welded Construction: Formed from one steel strip and longitudinally welded with external weld reinforcement removed for smooth surface.
Our Advantages
Dimensional Control: Precise management of the nonstandard 0.50 mm wall thickness
Weld-Seam Management: Controlled internal bead height and external scarfing for leak-proof performance
Stable Coil Processing: Consistent winding and traceability throughout production
