European foreword
This document (EN 10088-3:2023) has been prepared by Technical Committee CEN/TC 459 “ECISS -
European Committee for Iron and Steel Standardization ”, the secretariat of which is held by AFNOR.
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 June 2024, and conflicting national standards shall be
withdrawn at the latest by June 2024.
This document supersedes EN 10088-3:2014.
In comparison with the previous edition, the following technical modifications have been made:
a) addition of austenitic grades 1.4681, 1.4391, addition of austenitic-ferritic (duplex) grade 1.4670,
addition of ferritic grades 1.4106, 1.4114, 1.4045, addition of martensitic grade 1.4037;
b) chemical composition was changed for following grades: austenitic grades 1.4310, 1.4404, 1.4529,
ferritic grade 1.4003 and for martensitic grade 1.4028, 1.4116;
c) removal of austenitic grades, 1.4319, 1.4537;
d) mechanical values for bright bars have been changed for austenitic grades 1.4301, 1.4307 for ferritic
grades 1.4509, for martensitic grades 1.4028, 1.44418 and for austeno-ferritic grades 1.4362.
Mechanical values for bright bars have been added for martensitic grade 1.4021 in QT800 condition
and for 1.4057 in QT900 condition;
e) introduction of the possibility to use modelling for the determination of tensile properties;
f) columns have swapped places in Table 7 for better reading;
g) new Annex A lists all grades that appear in this document by ascending steel number.
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 C);
— Part 2: Technical delivery conditions for sheet/plate and strip of corrosion resistant steels for general
purposes;
— Part 3: Technical delivery conditions for semi-finished products, bars, rods, wire, sections and bright
products of corrosion resistant 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

1 Scope
This document specifies the technical delivery conditions for semi-finished products, hot or cold formed
bars, rods, wire, sections and bright products of standard grades and special grades of corrosion resistant
stainless steels for general purposes.
NOTE General purposes include the use of stainless steels in contact with foodstuffs.
The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of
this document, unless otherwise specified in this document.
This document does not apply to components manufactured by further processing of the product forms
listed above with quality characteristics altered as a result of such further processing.
