The wor

12、k of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governme

13、ntal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in th

14、e ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the poss

15、ibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list o

16、f patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

20、teel products ISO 2016 All rights reserved v Heat-treatable steels, alloy steels and free-cutting steels Part 1: Non-alloy steels for quenching and tempering 1 Scope This part of ISO 683 specifies the technical delivery requirements for semi-finished products, hot formed, e.g. blooms, billets, slabs

21、 (see Note 1), bars (see Note 1), wire rod, finished flat products, and hammer or drop forgings (see Note 1) manufactured from the direct hardening non-alloy steels and the non-alloy flame- and induction- hardening steels listed in Table 3 and supplied in one of the heat-treatment conditions given f

22、or the different types of products in Table 1 and in one of the surface conditions given in Table 2. The steels are, in general, intended for the manufacture of quenched and tempered or austempered (see 3.2 and Note 2) and flame- or induction-hardened machine parts (see Tables 9 and 11), but can als

23、o be partly used in the normalized condition (see Table 10). The requirements for mechanical properties given in this part of ISO 683 are restricted to the sizes given in Tables 9 and 10. NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-for

24、ged bars are, in the following, covered under semi-finished products or bars and not under the term “hammer and drop forgings”. NOTE 2 For the purposes of simplification, the term “quenched and tempered” is, unless otherwise indicated, used in the following also for the austempered condition. NOTE 3

25、 For International Standards relating to steels complying with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibl

26、iography. NOTE 4 This part of ISO 683 does not apply to bright products and bars and wire rod for cold heading. For such products, see ISO 683-18 and ISO 4954. In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement between the

27、manufacturer and purchaser at the time of enquiry and order (see 5.2 and Annex B). In addition to this part of ISO 683, the general technical delivery requirements of ISO 404 are applicable.INTERNATIONAL ST ANDARD ISO 683-1:2016(E) ISO 2016 All rights reserved 1 ISO 683-1:2016(E) 2 Normative referen

This correspond

37、s to the diameter of an “equivalent round bar”. That is a round bar which will show the same cooling rate as the actual ruling section of the product concerned at its position for taking the test pieces, when being cooled from austenitizing temperature. 3.2 austempering isothermal heat treatment for
