Full title and description
Standard Specification for General Requirements for Flat‑Rolled Stainless and Heat‑Resisting Steel Plate, Sheet, and Strip — ASTM A480/A480M‑25b. This document establishes the general requirements, testing, tolerances, marking, and purchase‑order conventions that apply to flat‑rolled stainless and heat‑resisting steels and that supplement the product‑specific ASTM specifications (for example A240/A240M and related product standards). The “25b” designation indicates the 2025 revision with incorporated amendments.
Abstract
ASTM A480/A480M‑25b sets uniform general requirements for flat‑rolled stainless and heat‑resisting steel plate, sheet, and strip, covering manufacture, chemical and mechanical testing, special tests (when required), dimensional and tolerance rules for both inch‑pound and SI (M) units, marking, certification, and rules for resolving conflicts between this general specification, product specifications, and purchaser requirements.
General information
- Status: Active (current edition).
- Publication date: 01 September 2025 (A480/A480M‑25b, includes subsequent amendments through 10 September 2025 where noted).
- Publisher: ASTM International.
- ICS / categories: 77.140.50 (Flat steel products and semi‑products) / Metals and metallurgy.
- Edition / version: A480/A480M‑25b (2025 revision, “M” denotes SI unit option where specified).
- Number of pages: 26 pages.
Scope
The specification covers a group of general requirements that apply, unless otherwise specified, to rolled stainless and heat‑resisting steel plate, sheet, and strip governed by product specifications such as A240/A240M and other related ASTM product specifications. It clarifies unit systems (inch‑pound and SI/M), test requirements, acceptance criteria, and the precedence between product specifications, this general specification, and purchaser requirements.
Key topics and requirements
- Applicability to flat‑rolled stainless and heat‑resisting steel plate, sheet, and strip.
- Chemical composition and heat analyses requirements for product conformance.
- Mechanical testing requirements (tension, hardness, bend) and procedures for required special tests (intergranular corrosion, permeability, Charpy impact, duplex intermetallic phase testing, etc.).
- Dimensional tolerances and unit system rules — inch‑pound and SI (A480M) with Annex guidance (Annex A3 for dimensional tolerances when A480M is specified).
- Requirements for marking, certification, mill test reports, and traceability of heat and product.
- Rules for resolving conflicts: product specification prevails over this specification, and purchaser requirements may supersede both unless they waive or reduce required tests or contravene the product specification.
- Options and supplement tests that may be specified by purchaser or product specification.
Typical use and users
Used by steel producers, mill quality/inspection personnel, third‑party testing laboratories, fabricators, procurement/specification engineers, design engineers, and end‑users who require consistent testing, marking, and acceptance criteria for flat‑rolled stainless and heat‑resisting steels supplied under ASTM product specifications.
Related standards
Commonly referenced with ASTM product specifications such as A240/A240M (stainless steel plate, sheet, and strip), and with A263, A264, A265, A666, A693, A793, and A895. Practitioners may also cross‑reference national and international standards dealing with stainless steels (for example EN/ISO standards on stainless steel grades, testing, and designation) and industry codes as applicable to the application.

FAQ
Q: What is this standard?
A: ASTM A480/A480M‑25b is the ASTM general‑requirements specification for flat‑rolled stainless and heat‑resisting steel plate, sheet, and strip, defining tests, tolerances, marking, and contractual precedence that apply unless a product specification states otherwise.
Q: What does it cover?
A: It covers manufacture, required chemical and mechanical tests, optional/special tests (intergranular corrosion, Charpy impact, permeability, duplex steel checks), dimensional/tolerance rules for inch‑pound and SI units, marking and certification, and rules for resolving conflicts between product specs, this standard, and purchase orders.
Q: Who typically uses it?
A: Steel mills, quality and inspection staff, testing labs, fabricators, procurement/specification engineers, and designers specifying or accepting flat‑rolled stainless or heat‑resisting steels.
Q: Is it current or superseded?
A: As of the publication information in this product description, the A480/A480M‑25b (published 01 September 2025, including noted amendments) is the current active edition. Users should confirm the status with ASTM or their standards provider for any updates after this date.
Q: Is it part of a series?
A: Yes — A480/A480M is a general‑requirements specification designed to be used in conjunction with ASTM product specifications (for example A240/A240M and other listed ASTM product standards) rather than as a standalone product specification.
Q: What are the key keywords?
A: flat‑rolled stainless, heat‑resisting steel, plate, sheet, strip, chemical analysis, mechanical testing, tolerances, A480, A480M, mill test report.
