适用范围

1 This part of ISO 4394 specifies the mechanical proper-ties, dimensional tolerances, surface finishes and technical delivery conditions for round steel tubes, seamless or welded type, hot or cold worked condition, with plain ends and having specially finished bores with or without metal removal. 2 The tubes defined by this part of ISO 4394 are intended for use as barreis in a wide variety of fluid power cylinders. NOTE — Steel should not be considered as the only material suitabie for such applications. 3 This part of ISO 4394 defines the tube dimensions by inside diameter and thickness, or inside diameter and outside diameter. 4 Annex A specifies the tolerances on outside diameters for cold finished or machined tubes. 5 Annex B establishes a range of preferred thicknesses for metric bore sizes for fluid power cylinders. Tables of thicknes-ses are included for both cold finished and hot finished steel tubes. 6 Annex C provides a recommended method of ordering.
