EN 10088-1:2014 (E) 3 Foreword This document (EN 10088-1:2014) has been prepared by Technical Committee ECISS/TC 105 “Steels for heat treatment, alloy steels, free-cutting and 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of an identical text or by endorsement, at the latest by April 2015 and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 10088-1:2005. This document mainly differs from the 2005 edition as follows: a) addition of austenitic grades 1.4615 (also part 3), 1.4618 (2), 1.4376 (2), 1.4640 (2), 1.4646 (2, 3), 1.4020 (3), 1.4378 (3), addition of austenitic-ferritic (duplex) grades 1.4162 (2, 3), 1.4662 (2, 3), 1.4658 (3), 1.4482 (2, 3), 1.4062 (2, 3), 1.4669 (3), addition of ferritic grades 1.4621 (2), 1.4600 (2), 1.4607 (2), 1.4611 (2, 3), 1.4613 (2, 3), 1.4630 (2), 1.4634 (2),addition of martensitic grade 1.4150 (3), addition of precipitation hardening grade 1.4612 (3); b) chemical composition was changed for following grades:austenitic grade 1.4371, 1.4597, austenitic-ferritic grade 1.4362. Each of the tables for the chemical composition of steel grades now has a sub-section with grades designated as 'uncommon' (i.e. not produced in the past 10 years and which may be removed during the next revision). EN 10088, under the general title Stainless steels, consists of the following parts: — Part 1: List of stainless steels (including a table of European Standards, in which these stainless steels are further specified, see Annex B) [the present document]; — Part 2: Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for general purposes; — Part 3: Technical delivery conditions for semi-finished products, bars, rods, wire, sections and bright products of corrosion resisting steels for general purposes; — Part 4: Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for construction purposes; — Part 5: Technical delivery conditions for bars, rods, wire, sections and bright products of corrosion resisting steels for construction purposes. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 10088-1:2014 (E) 4 Introduction The European Organization for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of patents applied to ten steel grades. CEN takes no position concerning the evidence, validity and scope of these patent rights. The holder of these patent rights has ensured CEN that they are willing to negotiate licences, under reasonable and non-discriminatory terms and conditions, with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with CEN.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10079:2007, Definition of steel products 3 Terms and definitions For the purposes of this document, the terms and definitions for the product forms given in EN 10079:2007 and the following apply. 3.1 stainless steels steels with at least 10,5 % of chromium and maximum 1,2 % of carbon [SOURCE: EN 10020:2000, 3.2.2] Note 1 to entry: Stainless steels are further subdivided in accordance with their main property into corrosion resisting steels, heat resisting steels and creep resisting steels. Note 2 to entry: One type of steel in Table 7 and five types of steel in Table 9 contain less chromium than the minimum defined for stainless steels, but are included in the heat-resisting and creep-resisting steels standards respectively, because they form a part of these two families of steels. 4 Chemical composition The chemical composition of stainless steels is given: — in Table 2 for austenitic corrosion resisting steels; — in Table 3 for austenitic-ferritic corrosion resisting steels; — in Table 4 for ferritic corrosion resisting steels; — in Table 5 for martensitic and precipitation hardening corrosion resisting steels; — in Table 6 for austenitic and austenitic-ferritic heat resisting steels; — in Table 7 for ferritic heat resisting steels; — in Table 8 for austenitic creep resisting steels; — in Table 9 for martensitic creep resisting steels. NOTE 1 The steel grades marked in Tables 2 to 9 as uncommon grades will be rechecked during the next revision and it will be decided whether to delete these steel grades or not. NOTE 2 The chemical composition of nickel and cobalt alloys listed in EN 10095, EN 10269 and EN 10302 is given in Tables F.1 and F.2. SIST EN 10088-1:2015

For bars, rods, wire, sections, bright products and the relevant semi-finished products, a maximum content of 0,030 % S applies. Particular ranges of sulfur content may provide improvement of particular

properties. For machinability a controlled sulfur content of 0,015 % to 0,030 % is recommended and permitted. For weldability, a controlled sulfur content of 0,008 % to 0,030 % is recommended and

permitted. For polishability, a controlled sulfur content of 0,015 % max. is recommended. c The stabilization may be made by use of Ti and/or Nb and/or Zr. According to the atomic mass of these elements and the content of Carbon and Nitrogen, the equivalence shall be the following:
