Full title and description

ISO 15510:2014 — Stainless steels — Chemical composition. This international standard consolidates and lists agreed chemical-composition limits and designation information for a wide range of stainless‑steel grades, harmonizing data from existing national and regional specifications (ISO, ASTM/UNS, EN, JIS, GB) for use with wrought product forms including ingots and semi‑finished material.

Abstract

ISO 15510:2014 lists the chemical compositions of stainless steels agreed by ISO/TC 17/SC 4, mainly on the basis of compositions from existing ISO, ASTM, EN, JIS and GB specifications. The tables and annexes apply to wrought product forms (including ingots and semi‑finished material) and provide cross‑references and a unified designation approach to aid grade selection and interchangeability.

Scope

Defines and lists chemical‑composition limits for a comprehensive set of stainless‑steel grades (austenitic, ferritic, duplex, martensitic and precipitation‑hardening categories) as agreed by ISO/TC 17/SC 4. The tables give elemental limits intended for cast analysis and are based on harmonization of existing national and regional specifications; the standard applies to all wrought product forms including ingots and semi‑finished material. Informative annexes provide cross‑references to other designation systems and additional guidance.

Key topics and requirements

• Consolidated table(s) of chemical‑composition limits (C, Si, Mn, P, S, Cr, Mo, Ni, N and other relevant elements) for many stainless‑steel grades.
• An ISO designation/numbering approach and cross‑reference tables that map ISO grades to EN, ASTM/UNS, JIS and GB equivalents to aid international procurement and substitution.
• Classification of grades by family (austenitic, ferritic, duplex, martensitic, precipitation‑hardening) and guidance on designation conventions.
• Normative and informative annexes (designation of comparable grades, cross‑references to other international standards, classification rules, density values and bibliography).
• Notes and guidance on application: tables are for composition limits (cast analysis) and any product‑specific deviations must be coordinated with technical committee provisions.

Typical use and users

Used as a reference for material engineers, metallurgists, procurement and design teams, steel producers and testing laboratories to select, compare and verify stainless‑steel grades internationally. Also used by standards committees and product specifiers to harmonize product specifications with internationally agreed chemical compositions.

FAQ

Q: What is this standard?

A: ISO 15510:2014 is the ISO international standard titled "Stainless steels — Chemical composition", which lists agreed chemical‑composition limits and designation information for a wide range of stainless‑steel grades.

Q: What does it cover?

A: It covers chemical‑composition limits for many stainless‑steel grades (elements and limits), a unified ISO designation approach and annexed cross‑references to other national and international designation systems; the composition tables are intended for cast analysis and apply to wrought product forms.

Q: Who typically uses it?

A: Material and design engineers, metallurgists, steel producers, mill‑test laboratories, procurement teams and standards committees involved in grade selection, specification and quality control.

Q: Is it current or superseded?

A: Edition 2 (2014) is the current published edition; the ISO record shows the 2014 edition was reviewed and confirmed (remaining current) after the 2019 review cycle.

Q: Is it part of a series?

A: It is part of ISO metallurgy/steel‑product standardization under ISO/TC 17/SC 4 and links to related ISO technical reports and specifications for steel names, terminology and related material standards (e.g., ISO/TS 4949, ISO 6929).

Q: What are the key keywords?

A: Stainless steel, chemical composition, steel grades, designation, austenitic, ferritic, duplex, martensitic, precipitation‑hardening, wrought products.
