It is the UK implementation of ISO/TS 15510:2003. This publication is not to be regarded as a British Standard. It is bei
3、ng issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on this provisional basis, so that information and experience of its practical application can be obtained. Comments arising from the use of this Draft for Development are requested so
4、that UK experience can be reported to the international organization responsible for its conversion to an international standard. A review of this publication will be initiated not later than 3 years after its publication by the international organization so that a decision can be taken on its statu
5、s. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into an international Standar
6、d, to extend the life of the Technical Specification or to withdraw it. Comments should be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK participation in its preparation was entrusted to Technical Committee
7、ISE/30, Stainless steels. A list of organizations represented on this committee can be obtained on request to its secretary.

10、00:00 2007, Uncontrolled Copy, (c) BSI iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member
11、 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elect
12、rotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopte
13、d by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technic
14、al committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee
15、 casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide
16、 whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Att
17、ention is drawn to the possibility 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. ISO/TS 15510 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and
18、 alloy steels.

19、 as a Technical Specification. It was nevertheless also stated that future discussions on ISO/TS 15510 should lead to a full ISO Standard.

20、Stainless steels Chemical composition 1 Scope This ISO Technical Specification lists the chemical compositions of stainless steels agreed by ISO/TC 17/SC 4 mainly on the basis of a composition of the specifications in existing ISO, ASTM, EN and JIS standards. They apply to all product forms includin
21、g ingots and semi-finished material. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments
22、) applies. ISO 6929:1987, Steel products Definitions and classification 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 6929 as well as the following apply. 3.1 stainless steel steel with at least 10,5 % mass fraction Cr and a maximum of 1,2 % mass f
23、raction C NOTE For the classification of stainless steels according to their structure, composition and application see Annex A. 4 Chemical composition The chemical composition of stainless steels approved by ISO/TC 17/SC 4 is given in Table 1. NOTE If, in special cases, e.g. an ISO committee charge
24、d with establishing or revising a standard for a specific product or application of stainless steels, sees the necessity of deviating from the specifications in Table 1 it should inform ISO/TC 17/SC 4 (Secretariats address: DIN, Postfach 10 51 45, 40042 Dsseldorf, Germany) of the reasons for this an
25、d try, before such deviations are considered, to achieve consensus for a corresponding modification to Table 1. 5 Designation of comparable steels In Table 2 are given the designations of stainless steels which are listed in other international, regional or national standards or designation systems
26、and are comparable to the grades in Table 1. NOTE To compare similar grades, it is necessary to check each element before making a substitution.
