Full title and description
ASTM A576-25 — Standard Specification for Steel Bars, Carbon, Hot‑Wrought, Special Quality. Specifies requirements for hot‑wrought special quality carbon steel bars intended for forging, heat treating, cold drawing, machining and related structural and manufacturing uses. Defines grades, chemical composition limits, mechanical property requirements, product forms (cut lengths and coils), and applicable supplementary requirements.
Abstract
This specification (A576, 2025 edition) covers hot‑wrought special quality carbon steel bars. It establishes grade designations and required chemical and mechanical properties, identifies permitted manufacturing processes (open‑hearth, basic‑oxygen, electric furnace), and sets provisions for product form, surface quality, heat treatment, and purchaser‑designated supplementary requirements. The standard references sizing/section limits in Specification A29/A29M and provides guidance for selection in Practice A400. Values are stated in inch‑pound units.

Scope
Applies to hot‑wrought special quality carbon steel bars furnished in specified grades and product forms (cut lengths and coils). The specification covers chemical composition limits, mechanical property requirements, surface quality, and optional supplementary requirements that purchasers may specify for tighter chemical restrictions, metallurgical characteristics, heat treatment, or finishes. Sections and sizes are referenced to Specification A29/A29M; merchant quality bars are covered separately in Specification A575.
Key topics and requirements
- Designations of special quality carbon steel grades and associated chemical composition limits (carbon, manganese, phosphorus, sulfur, etc.).
- Mechanical property criteria (tensile strength, yield, elongation) and required testing (tensile tests, hardness where applicable).
- Permitted primary steelmaking processes (open‑hearth, basic‑oxygen, electric furnace) and requirements for heat analysis.
- Product forms: cut lengths and coils; reference to A29/A29M for sections and sizes availability.
- Supplementary requirements allowing purchaser control over surface quality, heat treatment, special chemical restrictions, and metallurgical characteristics.
- Marking, certification, and conformity assessment requirements for deliveries.
- Use of inch‑pound units as the standard measurement system in the document.
Typical use and users
Used by steel producers, bar and rod manufacturers, metal distributors, product engineers, procurement specialists, quality and inspection laboratories, forging and machining shops, and design engineers specifying special‑quality carbon bar material for components that require defined chemistry and mechanical performance (forging, cold drawing, machining, heat treatment, structural applications).
Related standards
Commonly used together with: Specification A29/A29M (sections and sizes of bar steel), Practice A400 (guide for selection of steel bars), Specification A575 (merchant quality hot‑wrought carbon steel bars).
