3、ing permitted without license from IHS-,-,-Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 member bodies). The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member

4、body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. international organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical comm

5、ittees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. 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

16、 constructions such as metal bridges and frames. 2) At present at the stage of draft.

18、limination of defects 3.3.2.1 Minor defects may be removed by the manufacturer by grinding, provided that the thickness is not reduced locally by more than 7 % (with a maximum of 3 mm) in relation to its nominal value. 4 Characteristics of grades 4.1 Chemical composition 4.1.1 Ladle analysis The max

19、imum composition limits for analysis carried out on samples taken during casting are given in table 1. 4.1.2 Product analysis The maximum composition limits of the product are given in table 1. This analysis can be requested by the purchaser, in which case it shall be specified on the order. Table 1

21、operties specified in table 2 when these are determined on test pieces selected in accordance with 5.4. For products over 63 mm in thickness, the mechanical proper- ties shall be the subject of an agreement between the manufac- turer and the purchaser. 5 Acceptance testing 5.1 Rolled products Rolled

22、 products covered by this International Standard may be the subject of acceptance tests in accordance with the con- ditions specified in IS0 404 relating to the mechanical proper- ties and chemical analysis of the product. Verification of the chemical composition of the product is only carried out b

23、y agreement at the time of order. 5.2 Acceptance test unit If acceptance testing has been specified on the order, the ac- ceptance test unit is generally formed by cast; if agreed when ordering, it may be formed by batch). The acceptance test unit shall be - 20 t or fraction thereof for acceptance b

24、y batch; - 50 t or fraction thereof for acceptance by cast. 5.3 Types of tests 5.3.1 For each acceptance test or thickness range, as defined in table 2, the series of tests shall be carried out comprising - one tensile test (or more, in accordance with 5.3.3); - one product analysis, if agreed when

26、grade Fe 490; A 15 % for grade Fe 590; A 10 % for grade Fe 690; c) For other gauge lengths, reference shall be made to the conversion table (see IS0 2566/l). In case of dispute, however, only the results obtained on a pro- portional test piece will be taken into consideration. 5.5.1.3 The yield stre

27、ngth specified in the tables is the upper yield stress or the proof stress (0,5 % total elongation). If the 0,2 % proof stress (non-proportional elongation Rprr2) the lower yield stress I?, or proof stress (total elongation) Rt, is specified on the order, this specification is complied with in this

28、respect if the value obtained by such measurement satisfies the specified yield strength values in table 2. 5.5.2 Defective tests and test pieces 5.5.2.1 When a test does not give the required results because of an error in execution, the test shall be cancelled. 3 Copyright International Organizati

30、 independent of the metal itself. 5.5.2.2 If a defective test piece gives satisfactory results, the batch shall be accepted, but the corresponding item (from which the test sample was taken) shall be submitted to an in- dividual examination for soundness. 5.5.3 Supplementary tests If, when testing,

31、the required results are not achieved, ad- ditional tests unless otherwise agreed, shall be carried out as follows : 5.5.3.1 Tensile test 5.5.3.1.1 If the test piece does not give the required values, the corresponding item shall be deemed not to comply with the product specification unless two othe

32、r test pieces from the same item are tested and give satisfactory results. In this case, the item and the batch shall be considered to comply with the specification. 5.5.3.1.2 If one or both additional test pieces do not satisfy the requirements, the corresponding item shall be deemed not to comply

33、with the specification. In this case, the requirements of clause 6 may be applied. 5.5.4 Chemical analysis 5.5.4.1 In case of dispute, the method used for chemical analysis shall be in accordance with the requirements of the relevant International Standards. If no International Standards exist, the

34、method to be used shall be agreed between the in- terested parties. The samples may be taken from the test pieces used for verify- ing the mechanical properties or from drillings made from the full thicknesses of the product at the same place as the test pieces. In case of dispute, only the analysis

35、 of material taken from the full thickness of the product shall be taken into con- sideration. The requirements of IS0 37712 are to be applied when selec- ting and preparing samples for chemical analysis. 5.6 Documents The requirements of IS0 404 are to be applied. The type of cer- tificate required

36、 shall be specified in the order. 6 Resubmission (see IS0 404) 6.1 The producer may resubmit for inspection products which have been rejected during earlier inspection and which have subsequently been processed (selection, heat treatment), details of which shall be indicated to the purchaser on requ

37、est. In this case, tests shall be carried out as if they applied to a new batch. 6.2 The producer has the right to present rejected products for re-examination for another quality or grade. 7 Labelling Unless an agreement to the contrary is made at the time of the order, the products shall be legibl

38、y marked to show - the identification symbols for the grade of steel; - the brand of the manufacturer: - where necessary, symbols, letters or numbers which relate the test certificates, test pieces and products to each other. In the case of products of small unit mass and which are con- signed in ti

39、ed bundles, the labelling may only be in the form of a tag securely attached to each bundle (or it may be marked on the upper plate). 4 Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking permitted without license
