Draft International Standards adopted by the technical comm

International Standard IS0 1052 was developed by Technical Committee ISO/TC 17, Steel, and was circulated to the member bodies in March 1981. It has been approved by the mem

10、n the delivered state and as a rule in engineering structures.1) It does not deal with the following steels, which are dealt with in other International Standards : - steels for boilers and pressure vessels (IS0 26W4); - sheet for forming and stamping (IS0 3573 and IS0 3574); - structural steels for
11、 heat treatment; - bars for concrete; - general-purpose steels intended for metal construc- tions (IS0 630). 2 References IS0 62, Steel - Tensile testing.

14、rwise agreed at the time of ordering, the method of manufacture is left to the manufacturer; however, the user shall have the right to be informed of the method on request at the time of delivery. . The steels shall be non-rimming. 3.2 As-delivered condition The products are generally delivered in t
15、he as-rolled condition. Other as-delivered conditions may be agreed at the time of ordering. 1) Examples of applications of these steels are : Plates: machine frames Rounds: mechanical structure, not heat treated Fiats: agricultural machines, not heat treated These steels are not intended for welded
