18、I EN 10302:2002 (E) 3 Foreword This document EN 10302:2002 has been prepared by Technical Committee ECISS/TC 23, “Stainless steels“, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endo
19、rsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is considere
20、d to be a supporting standard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this European Standard. NOTE The clauses marked with a point (?) contain information relating to agreements whi
21、ch are to be made at the time of ordering. The clauses marked with two points (?) contain information relating to agreements which may be made at the time of ordering. The annexes A to D are informative. This European Standard contains a Bibliography. According to the CEN/CENELEC Internal Regulation
22、s, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the
23、 United Kingdom.

24、pment, for which the main requirement is their creep resistance under mechanical long-time stressing at temperatures above 500 ?C. Also heat resisting grades given in EN 10095 may be used for similar applications if so agreed. 1.2This European Standard specifies the technical delivery conditions for
25、 semi-finished products, for hot or cold rolled sheet/plate and strip, hot or cold formed (cold drawn) bars, rods, wire and sections. 1.3The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in th
26、is European Standard. 1.4This European Standard does not apply to components manufactured by further processing the product forms listed in 1.2 with quality characteristics altered as a result of such further processing. 1.5This European Standard is not intended for aerospace and pressure purposes.
27、1.6For steels and alloys with similar chemical composition, but intended for different applications, see the Bibliography. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropr
28、iate places in the text, and the publications are listed hereafter.

35、echanical behaviour at temperatures above 500 ?C under long-range service conditions; i. e. primarily by high creep strength or high rupture strength during long-time stressing NOTE For supplementary information on creep resisting steels and alloys see annex B. 4 Classification and designation 4.1Cl
36、assification Materials covered in this European Standard are classified according to their structure into: ? martensitic steels; ? austenitic steels; ? nickel alloys; and ? cobalt alloys. 4.2Designation The names and numbers of the steels (see Table 1) were formed in accordance with EN 10027-1 and E
