Overview
EN 10088-1:2023 - Stainless steels - Part 1: List of stainless steels is the Slovenian adoption of EN 10088-1:2023. This part of the EN 10088 series provides a comprehensive list of stainless steel grades and the chemical composition ranges for each grade. Grades are grouped by primary performance: corrosion resistant, heat resistant, and creep resistant steels. The standard references material standards (Table 1) and includes informative annexes with designation cross‑references, classification rules, empirical formulae and guidance data on physical properties.
Key technical topics and requirements
- Chemical composition tables: Detailed cast/analysis composition ranges are given in Tables 2–9 for:
- Austenitic corrosion resistant steels
- Austenitic‑ferritic (duplex) corrosion resistant steels
- Ferritic corrosion resistant steels
- Martensitic and precipitation‑hardening corrosion resistant steels
- Austenitic and austenitic‑ferritic heat resistant steels
- Ferritic heat resistant steels
- Austenitic creep resistant steels
- Martensitic creep resistant steels
- Microstructure & pitting resistance: Annex D provides empirical formulae for microstructure classification and pitting resistance ranking - useful for material selection against localized corrosion.
- Physical property guidance: Annex E contains reference data (Tables E.1–E.8) on selected physical properties relevant to design and engineering.
- Cross‑reference & designation: Annex A lists ISO and comparable designations; Annex B presents a matrix mapping which steels are covered by which European material standards.
- Normative scope and notes: The document clarifies that valve steels, castings, tool steels and welding consumables are covered by other standards (e.g., EN 10090, EN ISO 4957) and flags that a small number of grades are subject to patent claims.
Practical applications and users
This standard is essential for:
- Material engineers and metallurgists selecting stainless steel grades for corrosion, temperature and creep performance
- Product designers and structural engineers specifying materials for equipment, piping, pressure vessels and heat‑exposed components
- Procurement and quality managers ensuring purchased materials meet European grade definitions
- Manufacturers, fabricators and testing laboratories verifying chemical composition and conformity to European material standards
- Standards bodies and spec writers mapping international designations to European grade numbers
Related standards
- EN 10088 series (Parts 2–5) - technical delivery conditions for sheet, plate, bars and semi‑finished products
- EN 10090 (valve steels), EN ISO 4957 (tool steels)
- EN 10095, EN 10269, EN 10302 (nickel/cobalt alloys referenced in Annex F)
- Various material standards listed in Table 1 of the standard
Keywords: EN 10088-1:2023, stainless steels, chemical composition, corrosion resistant steels, heat resistant steels, creep resistant steels, stainless steel grades, microstructure classification, pitting resistance, European standard.

Elements not quoted (“-”) or 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
shall 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.
a
Maximum values unless indicated otherwise.
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 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
0,0080 % to 0,030 % is recommended and permitted. For polishability, a controlled sulfur content of 0,015 % max. is recommended.
c
For austenitic steel grades intended for cold heading and cold extruding, a Cu-content of max. 1,00 % is permitted.
d
Where for special reasons, e.g. hot workability for the fabrication of seamless tubes where it is necessary to minimize the delta ferrite content, or with the aim of low magnetic permeability,
the maximum Ni content may be increased by the following amounts:
- 0,50 % (m/m): 1.4571;
- 1,00 % (m/m): 1.4306, 1.4406, 1.4429, 1.4434, 1.4436, 1.4438, 1.4541, 1.4550;
- 1,50 % (m/m): 1.4404.
e
Parts made of high sulfur free cutting austenitic steels may not comply with European Directive 94/27 regarding articles in contact with human skin.
f
For pressure purposes a carbon limit of C ≤ 0,07 % is allowed.
g
For application according to Pressure Equipment Directive (PED) 2014/68/EU the phosphorus content is restricted to max 0,035 %.

Elements not quoted 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 shall 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.
a
Maximum values unless indicated otherwise.
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 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:
Nb (% by mass) ≡ Zr (% by mass) ≡ 7/4 Ti (% by mass).
d
Ti + Nb: 8×(C + N) to 0,80 %.
