36、 for the machining of circular rings, flanges, shafts, etc, having a wall thickness which is a substantial proportion of the outer diameter; such tubing is not usually used for the transmission of fluids and parts made from it are usually machined all over. This product is sometimes known as “hollow
37、 bar“.8.4 Dimensions in inch/pound units are primary; dimensions in SI units are shown as the approximate equivalents of the primary units and are presented only for information.SAE INTERNATIONAL AMS5024H Page 6 of 7_ 8.5 Purchase documents should specify not less than the following:AMS 5024GForm and size or part number of product desiredQuantity of product desired.PREPARED UNDER THE JURISDICTION OF AMS COMMITTEE “E“SAE INTERNATIONAL AMS5024H Page 7 of 7_
