23、017-01 EN 10027-1:2016 (E)5 1 Scope 1.1 This European Standard specifies rules for designating steels by means of symbolic letters and numbers to express application and principal characteristics, e.g. mechanical, physical, chemical, so as to provide an abbreviated identification of steels. NOTE In
24、the English language the designations covered by this European Standard are known as “steel names”; in the French language as “designation symbolique”; in the German language as “Kurznamen”. 1.2 This European Standard applies to steels specified in European Standards (EN), Technical Specifications (
25、TS), Technical Reports (TR) and CEN members national standards. 1.3 These rules may be applied to non-standardized steels. 1.4 A system of numerical designation of steels known as steel numbers is specified in EN 10027-2. 2 Normative references The following documents, in whole or in part, are norma
26、tively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10020:2000, Definition and classification of grades of stee
27、l EN 10027-2, Designation systems for steels - Part 2: Numerical system EN 10079:2007, Definition of steel products 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 10020:2000 and EN 10079:2007 apply. 4 Principles 4.1 A unique steel name There shall be
28、 one unique steel name for each steel. 4.2 Formulation of steel names Steel names allocated in accordance with this European Standard shall comprise principal symbols as specified in 7.1. In order to avoid ambiguity, it may be necessary to supplement these principal symbols by additional symbols ide
29、ntifying additional characteristics of the steel or steel product, e.g. suitability for use at high or low temperatures, surface condition, treatment condition, de-oxidation. These additional symbols are given in 7.2. DIN EN 10027-1:2017-01EN 10027-1:2016 (E) 6 Unless otherwise specified in this Eur
30、opean Standard the symbols used in the steel name shall be written without spaces. 4.3 Allocation of steel names 4.3.1 For steels specified in European Standards (EN), Technical Specifications (TS) and Technical Reports (TR), steel names shall be allocated by the ECISS Technical Committee concerned.
31、 4.3.2 For steels specified in CEN members national standards and for other steels, steel names shall be allocated by or under the responsibility of the national standards body concerned. So as to avoid a variety of steel names being assigned to essentially the same steel, the European Registration
32、Office as provided for in EN 10027-2 shall, when a steel number is applied for, cooperate with the national standards body concerned to ensure uniform steel names. 4.4 Consultation Where there are difficulties or disputes in establishing steel names ECISS/TC100 shall be consulted and shall advise ac
33、cordingly. 5 Reference to product standards The complete designation of a steel product where quoted in orders or similar contractual documents shall include, in addition to the steel name, an indication of the technical delivery requirement in which the steel is specified. For steels specified in s
34、tandards this shall be the reference number of the relevant product standard. Details of the structures of the steel name for the steel or steel product shall be provided in the relevant product or dimensional standard. 6 Classification of steel names For the purposes of designation, steel names are
35、 classified into two main categories: Category 1: steels designated according to their application and mechanical or physical properties (see 7.3). Category 2: steels designated according to their chemical composition (see 7.4). 7 Structure of steel names 7.1 Principal symbols Principal symbols for
36、steels designated according to steel application and its mechanical and physical properties shall be assigned in accordance with 7.3. Principal symbols for steels designated according to the chemical composition of the steel shall be assigned in accordance with 7.4. Where a steel is specified in the
37、 form of a steel casting, its name as specified in Tables 1 to 15 shall be preceded by the letter G. Where a steel is produced by powder metallurgy, its name as specified in Tables 14 and 15 shall be preceded by the letters PM. DIN EN 10027-1:2017-01 EN 10027-1:2016 (E) 7 7.2 Additional symbols Addi
38、tional symbols may be added to the principal symbols and assigned in accordance with 7.3 and 7.4. Additional symbols are divided into two groups, i.e. group 1 and group 2 (see 7.3 and 7.4). If the symbols for group 1 are inadequate to describe the steel fully, then additional symbols from group 2 ma
39、y be added. Symbols of group 2 shall only be used in conjunction with and follow symbols of group 1. Further additional symbols for steel products may follow the additional symbols of group 1 and group 2 and shall be selected in accordance with 7.3 and 7.4 from Tables 16, 17 and 18. These symbols sh
40、all be separated from preceding symbols by the plus sign (+). Additional symbols selected from Tables 16, 17 and 18 may be added to steel numbers allocated in accordance with EN 100272 and, when used, separated from the steel number by the plus sign (+). 7.3 Steels designated according to their appl
41、ication and mechanical or physical properties The designation of steel according to their application and mechanical or physical properties shall be made in accordance with Table 1 to Table 11.
