Steel J525 Round Tube 7/8" OD x 0.035" wall Price

About J525|SAE J525 mechanical tubing specification. Covers welded or seamless, cold-drawn, low-carbon steel tubing for hydraulic lines, mechanical applications, and fluid power systems. The spec ensures dimensional accuracy, surface finish, and mechanical properties suitable for bending and flaring. Not a material grade itself but a manufacturing spec. The steel underneath is typically 1008-1020 range. If you see J525 on a PO, the customer cares about tube quality and dimensional precision, not just the base alloy. Compare to A500 (structural tubing, lower precision) and DOM tubing (drawn over mandrel, similar quality concept).

About Round Tube|Hollow cylindrical stock for sleeves, bushings, spacers, and hydraulic cylinders. DOM (drawn over mandrel) tubing machines well and holds tight tolerances. Welded-seam structural tube is for cutting and welding, not precision work.
