European foreword
This document (prEN 10088-2:2021) has been prepared by Technical Committee CEN/TC 459/SC 5
“Steels for heat treatment, alloy steels, free-cutting steels and stainless steels”, stainless steels, the
secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 10088-2:2014.
In comparison with the previous edition, the following technical modifications have been made:
— addition of austenitic grade 1.4382, 1.4682, 1.4420, 1.4678, austenitic-ferritic grade 1.4637, ferritic
grade 1.4622, martensitic grade 1.4060.
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);
— 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
resisting steels for construction purposes.

1 Scope
This document specifies the technical delivery conditions for hot or cold rolled sheet/plate and strip 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 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.
