Full title and description
ASTM A615/A615M-24 — Standard Specification for Deformed and Plain Carbon‑Steel Bars for Concrete Reinforcement. This specification defines chemical, mechanical, dimensional, marking and testing requirements for deformed and plain carbon‑steel reinforcing bars supplied in cut lengths or coils for use in reinforced concrete.
Abstract
This standard covers deformed and plain carbon‑steel bars for concrete reinforcement, including specified minimum yield levels (Grades 40, 60, 80 and 100), required heat analysis, tensile and elongation properties, deformation patterns, bending/tension tests, and marking. The specification is published in dual designation (A615 in inch‑pound units and A615M in SI units).
General information
- Status: Historical / superseded — A615/A615M‑24 was published in 2024 and has been superseded by a later edition (A615/A615M‑25, published in 2025).
- Publication date: 15 May 2024 (approved/published in mid‑2024).
- Publisher: ASTM International.
- ICS / categories: 77.140.15 — Steels for reinforcement of concrete (reinforcing bars).
- Edition / version: A615/A615M‑24 (2024 edition); listed in ASTM document history prior to the 2025 revision.
- Number of pages: 8 pages (typical published PDF length).
Scope
The specification applies to deformed and plain carbon‑steel bars in cut lengths and coils for concrete reinforcement (and, via Annex A2, deformed bars for other uses). It sets requirements for bar sizes and number designations, minimum yield strengths (Grades 40, 60, 80, 100), chemical composition limits, required mechanical tests (tension, yield, elongation), bend tests, deformation profiles, marking, and available supply forms (cut lengths and coils). The document is available in both inch‑pound and SI units as dual designations.
Key topics and requirements
- Designated grades and minimum yield strengths: Grade 40 (≈280 MPa), Grade 60 (≈420 MPa), Grade 80 (≈550 MPa) and Grade 100 (≈690 MPa).
- Chemical composition controls (carbon, manganese, phosphorus, sulfur) and heat identification requirements.
- Mechanical property requirements: specified tensile strength, yield strength and elongation limits, plus required tension and bend tests.
- Dimensional tables and standard bar sizes/number designations (including large sizes up to No. 20 where noted).
- Supply forms, marking, packaging, and requirements for cut lengths and coils; guidance on welding and special applications (annexes/notes).
Typical use and users
Used by structural engineers, reinforcing‑steel fabricators, rebar suppliers, concrete contractors, materials laboratories, code writers, and procurement/specification authors who require standardized mechanical and chemical requirements for reinforcing bars used in concrete construction. It is referenced in purchasing specifications, construction contracts, and design documentation for reinforced concrete elements.
Related standards
Commonly used alongside other ASTM standards and industry documents such as A706/A706M (low‑alloy deformed and plain bars), A6/A6M (general requirements for rolled steel), A370 (mechanical testing of steel), A510/A510M (wire rod requirements), and A700 (packaging/marking guidance). It is prepared under ASTM Committee A01 (Subcommittee A01.05 on steel reinforcement).

FAQ
Q: What is this standard?
A: ASTM A615/A615M‑24 is a 2024 ASTM specification that sets chemical, mechanical, dimensional and testing requirements for deformed and plain carbon‑steel bars used as reinforcement in concrete.
Q: What does it cover?
A: It covers bar sizes and designations, minimum yield strength grades (40, 60, 80, 100), required heat analysis and composition limits, tensile/yield/elongation requirements, required tests (tension/bend), deformations and marking, and supply forms (cut lengths and coils).
Q: Who typically uses it?
A: Structural engineers, concrete contractors, rebar suppliers and fabricators, materials/test laboratories, specifiers, and procurement teams for construction and precast concrete projects.
Q: Is it current or superseded?
A: As of today (February 20, 2026) A615/A615M‑24 is a 2024 edition that has been superseded by a later ASTM revision (A615/A615M‑25 published in 2025); A615/A615M‑24 is therefore historical/superseded. Records show the 2024 edition published May 15, 2024 and the 2025 revision later in the ASTM document history; some bibliographic services also report A615/A615M‑24 as withdrawn in late 2025.
Q: Is it part of a series?
A: Yes — it is part of ASTM's suite of steel and reinforcing‑steel standards developed by Committee A01 (Subcommittee A01.05). It is commonly referenced together with related ASTM specifications for reinforcing steel (for example A706/A706M) and with ASTM test‑method standards used for verification.
Q: What are the key keywords?
A: Rebar, reinforcing bar, deformed bar, plain bar, carbon‑steel, A615, A615M, Grade 40, Grade 60, Grade 80, Grade 100, tensile, yield, bend test.
