ASTM A519 1020 Honed Seamless Steel Tube

The Honed Steel Tubing is made of cold-rolled Precision Steel Pipe finished product or Steel Pipe waste pipe, after pickling, phosphating, saponification treatment, and then rolled by cold-drawing machine to become hydraulic steel pipe. The precision of the hydraulic cylinder can generally be controlled within the range of 0.02-0.05mm, and the allowable deviation of the inner diameter is 0.03mm. Hydraulic cylinder tube st52 din2391 widely used in hydraulic system with precision steel tube, injection molding machine with precision steel tube, hydraulic press with precision steel tube, shipbuilding with steel tube, EVA foaming, hydraulic machinery, hydraulic cutting machine, shoe making machinery, hydraulic equipment, high pressure tubing, hydraulic tubing, card sets of joints, pipe joints, rubber machinery, forging machinery, casting machinery, engineering machinery, automotive high pressure steel pipe concrete pump, sanitation vehicle, automob…
