Product Detail

Good Mechanical Property EN10305-1 E355+SR Honed Seamless Steel Hydraulic Cylinder Tube And Tubing

Hydraulic Cylinder steel Tube is a kind of after cold rolling processing of a kind of high precision steel tube, full name cold rolled precision seamless steel tube. Hydraulic tubing wall inside and outside is without oxidation layers, under high pressure without destroy, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc. It is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, usually made  made from seamless tube. The chemical composition Hydraulic Cylinder Tube with carbon sulfur C, Si, Mn, S, P, and Cr.
