ASTM A1008/A1008M-25 PDF

Full title and description

ASTM A1008/A1008M-25 — Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, Required Hardness, Solution Hardened, and Bake Hardenable. The specification covers cold-rolled carbon steel sheet in coils and cut lengths across a wide range of designations (commercial, drawing, deep-drawing, structural grades, HSLAS and HSLAS-F, solution‑hardened, and bake‑hardenable steels) and defines chemical, mechanical, and surface requirements and testing.

Abstract

This specification defines the available cold‑rolled sheet designations (CS, DS, DDS, EDDS, SS grades, HSLAS classes, HSLAS‑F, SHS, BHS), requires heat analysis for chemical conformance, and prescribes tensile, yield, elongation, bending tests and bake hardening index where applicable. Sheet surfaces are generally matte and oiled unless otherwise specified. Units are given in inch‑pound and SI (each system used independently).

Scope

The standard applies to cold‑rolled carbon steel sheet, supplied in coils or cut lengths, covering commercial steels (CS), drawing steels (DS), deep and extra‑deep drawing steels (DDS, EDDS), structural grades (SS with multiple yield/tensile levels), high‑strength low‑alloy steels (HSLAS) including improved‑formability variants (HSLAS‑F), solution‑hardened steels (SHS) and bake‑hardenable steels (BHS). It excludes steel strip as described in Specification A109/A109M. Both SI and inch‑pound units are provided and are to be used independently.

Key topics and requirements

• Designation matrix covering CS, DS, DDS, EDDS, SS grades, HSLAS, HSLAS‑F, SHS, and BHS.
• Chemical composition verification by heat analysis; composition limits for each designation.
• Mechanical property requirements: yield strength, tensile strength, elongation and specified bending behavior per designation.
• Bake hardening index requirements and test methods for bake‑hardenable grades.
• Required hardness and solution‑hardened requirements where specified.
• Surface condition: matte finish and oiled unless otherwise specified; note on applicability relative to coated or hot‑rolled specifications (A653/A1011 etc.).
• Independent use of SI and inch‑pound units (do not combine values from both systems).

These requirements are summarized from the standard text and official listing.

Typical use and users

Commonly used by steel producers, metal fabricators, automotive and appliance manufacturers, architectural and building product specifiers, procurement and quality engineers, and standards committees. The specification is frequently referenced in construction and building specifications for cold‑rolled components where specific sheet grades and mechanical properties are required.

Related standards

Related or cross‑referenced standards include ASTM A109/A109M (steel strip — excluded from this specification), ASTM A653/A653M (zinc‑coated/galvanized sheet — referenced for harmonization of some required‑hardness provisions), and ASTM A1011/A1011M (hot‑rolled sheet and strip) among others addressing coating, strip, and processing. Ongoing work items note harmonization activity with A653 for required hardness sections.

FAQ

Q: What is this standard?

A: ASTM A1008/A1008M-25 is the ASTM standard specification that defines types, designations, chemical and mechanical requirements, and testing for cold‑rolled carbon steel sheet supplied in coils or cut lengths.

Q: What does it cover?

A: It covers a wide range of cold‑rolled sheet designations (commercial, drawing, deep drawing, structural grades, high‑strength low‑alloy and improved‑formability variants, solution‑hardened and bake‑hardenable steels), specifying composition by heat analysis and mechanical tests (tensile, yield, elongation, bending, bake‑hardening index) and surface condition. It does not apply to steel strip described in ASTM A109/A109M.

Q: Who typically uses it?

A: Steel mills, metal fabricators, automotive and appliance manufacturers, construction specifiers, procurement and QA/QC engineers, and designers who require defined cold‑rolled sheet grades and verified mechanical/chemical properties.

Q: Is it current or superseded?

A: The A1008/A1008M-25 edition is listed as the active (2025) edition; ASTM's product listing shows the -25 document as active and records a last‑updated entry (Dec 8, 2025) on the ASTM store. Users should refer to the ASTM catalog or official ASTM Compass/Digital Library for the most current status before applying the standard.

Q: Is it part of a series?

A: Yes — A1008/A1008M is part of ASTM's family of steel sheet and strip specifications and is commonly coordinated with related designations (for example A109/A109M for strip, A653/A653M for coated sheet, A1011/A1011M for hot‑rolled sheet). Subcommittee A01.19 develops and maintains the document.

Q: What are the key keywords?

A: cold‑rolled steel sheet, carbon sheet, commercial steel (CS), drawing steel (DS), deep drawing (DDS/EDDS), structural steel (SS grades), high‑strength low‑alloy (HSLAS/HSLAS‑F), solution hardened (SHS), bake hardenable (BHS), bake hardening index, heat analysis, tensile and yield strength.
