text or by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn
at the latest by December 2005.
This document supersedes EN 10088-1:1995.
EN 10088, under the general title "Stainless steels", consists of the following parts:

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 10079:1992, Definition of steel products

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions for the product forms given in EN
10079:1992 and the following apply.
3.1
stainless steels
stainless steels are steels with at least 10,5 % of chromium and maximum 1,2 % of carbon
[see EN 10020:2000, definition 3.2.2]
They are further subdivided in accordance with their main property into corrosion resisting steels, heat
resisting steels and creep resisting steels
NOTE One steel in Table 6 and five in Table 8 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 ferritic corrosion resisting steels;
in Table 3 for martensitic and precipitation hardening corrosion resisting steels;
in Table 4 for austenitic corrosion resisting steels;
in Table 5 for austenitic-ferritic corrosion resisting steels;
in Table 6 for ferritic heat resisting steels;
in Table 7 for austenitic and austenitic-ferritic heat resisting steels;
in Table 8 for martensitic creep resisting steels;
in Table 9 for austenitic creep resisting steels.
NOTE The chemical composition of nickel and cobalt alloys listed in EN 10095, EN 10269 and EN 10302 is given in
Tables E.1 and E.2.

a
Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast. All appropriate precautions are to be taken to avoid the addition
of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the steel.
b
For bars, rods, wire, sections, bright products and the relevant semi-finished products, a maximum content of 0,030 % S applies. Particular ranges of sulphur content may provide improvement of particular
properties. For machinability a controlled sulphur content of 0,015 % to 0,030 % is recommended and permitted. For weldability, a controlled sulphur content of 0,008 % to 0,030 % is recommended and
permitted. For polishability, a controlled sulphur content of 0,015 % max. is recommended.
c
The stabilisation may be made by use of titanium or niobium or zirconium. According to the atomic mass of these elements and the content of carbon and nitrogen, the equivalence shall be the following:
Nb (% by mass) ≡ Zr (% by mass) ≡ 7/4 Ti (% by mass).
