Full title and description
ASTM A1011/A1011M-25 — Standard Specification for Steel, Sheet and Strip, Hot‑Rolled, Carbon, Structural, High‑Strength Low‑Alloy, High‑Strength Low‑Alloy with Improved Formability, and Ultra‑High‑Strength. This edition (‑25) consolidates designations for commercial, drawing, structural, HSLAS, HSLAS‑F, and UHSS hot‑rolled sheet and strip offered in coils and cut lengths, and defines required chemical, mechanical and test criteria for each designation.
Abstract
This specification covers hot‑rolled carbon and alloy steel sheet and strip in a broad range of designations (CS, DS, SS, HSLAS, HSLAS‑F, UHSS). It sets heat and product analysis requirements, mechanical property limits (yield, tensile, elongation) for most designations, and mandatory tests such as tension and bending; units are provided in both inch‑pound and SI (A1011/A1011M) formats.
General information
- Status: Active standard (2025 edition, A1011/A1011M‑25).
- Publication date: 2025 (A1011/A1011M‑25 edition).
- Publisher: ASTM International.
- ICS / categories: 77.140.20 (Steels of high quality) — hot‑rolled sheet and strip categories.
- Edition / version: A1011/A1011M‑25 (2025 edition).
- Number of pages: 8 (official publication page count).
Scope
The standard applies to hot‑rolled steel sheet and strip (coils and cut‑lengths) covering Commercial Steels (CS Types A–D), Drawing Steels (DS Types A–B), Structural Steels (SS Grades 30–80), High‑Strength Low‑Alloy steels (HSLAS Grades 45–70), HSLAS with improved formability (HSLAS‑F Grades 50–80), and Ultra‑High‑Strength steels (UHSS Grades 90–100). It excludes steels covered by A635/A635M and provides both inch‑pound and SI requirements; separate metric and imperial values are to be used independently.
Key topics and requirements
- Designation structure and grade tables for CS, DS, SS, HSLAS, HSLAS‑F, and UHSS with corresponding yield/tensile targets.
- Chemical composition limits and required heat/product analyses (C, Mn, P, S, Al, Si, Cu, Ni, Cr, Mo, V, Nb, Ti, N, B).
- Mechanical property testing: mandatory tension tests (typically two specimens for non‑CS/DS grades), yield, tensile, elongation requirements, and bending tests.
- HSLAS‑F and UHSS-specific formability and strength considerations, including improved inclusion control and microalloying options.
- Units and tolerances: separate inch‑pound and SI values; combining values from both systems may lead to nonconformance.
- Marking, mill test reports (MTRs) and required documentation for acceptance and traceability.
Typical use and users
Common users include steel mills, service centers, fabricators, automotive and transport OEMs, agricultural and construction equipment manufacturers, and specifiers for general‑purpose structural components and formed parts. Typical applications are coils and cut lengths for stamping, bending, welded structures, battery enclosures, panels, and other formed components where cost‑effective hot‑rolled steel is acceptable.
Related standards
Related and historically linked standards include ASTM A568 (general requirements referenced by hot‑rolled sheet specs), previous A1011 editions (e.g., A1011/A1011M‑18 and earlier), Specification A635/A635M (excluded by scope), and industry documents that reference A1011 grades (automotive and construction codes). Users commonly cross‑reference EN and SAE equivalents for specific grades.

FAQ
Q: What is this standard?
A: ASTM A1011/A1011M‑25 is the 2025 edition of the ASTM standard that specifies requirements for hot‑rolled carbon and alloy steel sheet and strip in coils and cut lengths across a range of commercial, drawing, structural, HSLA, HSLA‑F and UHSS designations.
Q: What does it cover?
A: It covers designation tables, chemical composition limits, mechanical property requirements (yield, tensile, elongation), required tests (tension, bending), documentation (MTRs), and dual unit (inch‑pound and SI) provisions for hot‑rolled sheet and strip. It explicitly excludes steels covered by A635/A635M.
Q: Who typically uses it?
A: Steel producers, distributors, fabricators, OEM engineering teams (automotive, agricultural, construction), procurement/specification engineers, and quality inspectors use A1011 to specify and verify hot‑rolled sheet and strip supplied in coils or cut lengths.
Q: Is it current or superseded?
A: The A1011/A1011M‑25 edition is the current 2025 edition of the specification. Users should confirm the edition required by contract or project; the ASTM document for the edition contains the definitive, enforceable text.
Q: Is it part of a series?
A: Yes — A1011 is part of ASTM's family of steel product specifications and has absorbed or replaced several earlier hot‑rolled sheet specs (e.g., A568, A570 series historically); it is maintained by ASTM subcommittee A01.19 and is published alongside other related steel specifications.
Q: What are the key keywords?
A: Hot‑rolled, sheet, strip, commercial steel, drawing steel, structural steel, HSLAS, HSLAS‑F, UHSS, mechanical properties, chemical composition, mill test report.
