Foreword

This document (EN 10088-12014) has been prepared by Technical Committee ECISSTC 105 ldquoSteels for heat treatment alloy steels free-cutting and stainless steelsrdquo 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of an identical text or by endorsement at the latest by April 2015 and conflicting national standards shall be withdrawn at the latest by April 2015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 [andor CENELEC] shall not be held responsible for identifying any or all such patent rights

This document supersedes EN 10088-12005

This document mainly differs from the 2005 edition as follows

a) addition of austenitic grades 14615 (also part 3) 14618 (2) 14376 (2) 14640 (2) 14646 (2 3) 14020 (3) 14378 (3) addition of austenitic-ferritic (duplex) grades 14162 (2 3) 14662 (2 3) 14658 (3) 14482 (2 3) 14062 (2 3) 14669 (3) addition of ferritic grades 14621 (2) 14600 (2) 14607 (2) 14611 (2 3) 14613 (2 3) 14630 (2) 14634 (2)addition of martensitic grade 14150 (3) addition of precipitation hardening grade 14612 (3)

b) chemical composition was changed for following gradesaustenitic grade 14371 14597 austenitic-ferritic grade 14362

Each of the tables for the chemical composition of steel grades now has a sub-section with grades designated as uncommon (ie 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

mdash 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]

mdash Part 2 Technical delivery conditions for sheetplate and strip of corrosion resisting steels for general purposes

mdash Part 3 Technical delivery conditions for semi-finished products bars rods wire sections and bright products of corrosion resisting steels for general purposes

mdash Part 4 Technical delivery conditions for sheetplate and strip of corrosion resisting steels for construction purposes

mdash 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

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 Information may be obtained from

2 Normative references

The following referenced documents in whole or in part are normatively 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 100792007 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 100792007 and the following apply

31 stainless steels steels with at least 105 of chromium and maximum 12 of carbon

[SOURCE EN 100202000 322]

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

mdash in Table 2 for austenitic corrosion resisting steels

mdash in Table 3 for austenitic-ferritic corrosion resisting steels

mdash in Table 4 for ferritic corrosion resisting steels

mdash in Table 5 for martensitic and precipitation hardening corrosion resisting steels

mdash in Table 6 for austenitic and austenitic-ferritic heat resisting steels

mdash in Table 7 for ferritic heat resisting steels

mdash in Table 8 for austenitic creep resisting steels

mdash 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 F1 and F2
