GOST 2590-2006 PDF

Full title and description

GOST 2590-2006 — Round hot-rolled steel bars. Assortment (dimensions and tolerances) — an interstate standard that specifies the assortment, nominal sizes, dimensional tolerances, rolling accuracy and related requirements for hot‑rolled round steel bars used across industry.

Abstract

This standard defines the dimensional assortment, length and curvature classes, ovality and allowable deviations for hot‑rolled round steel bars. It sets rolling accuracy classes, length tolerances and basic requirements for use in engineering, construction and manufacturing where round bar blanks are required.

Scope

GOST 2590-2006 applies to hot‑rolled round steel bars and defines the assortment (nominal diameters and permitted dimensional ranges), length groups, straightness/curvature classes, ovality limits and rolling accuracy categories. The standard covers a broad diameter range used in industry (commonly referenced as covering from small bar sizes up to several hundred millimetres in diameter, with practical implementations and national adaptations listing ranges such as ~5 mm up to 270 mm) and aligns its assortment requirements with international practice (notably correspondence with EN 10060:2003 in terms of assortment principles).

Key topics and requirements

• Defined assortment of nominal bar diameters and permissible deviations for each size.
• Rolling accuracy classes (precision/quality grades) and surface/shape tolerances.
• Length groups, length tolerances and allowable deviations in overall bar length.
• Straightness/curvature classes and limits on bar curvature.
• Ovality (deviation from circular cross‑section) limits and measurement rules.
• Conformity rules relating assortment to steel grades and manufacturing practice.

Typical use and users

Steel producers, metal service centers, distributors and procurement departments use GOST 2590-2006 to specify and verify hot‑rolled round bar dimensions and tolerances for supply contracts. Engineering designers, machinists and manufacturers reference it when selecting blanks for machining, forging, fastener production, shafts, axles and construction components where round bar geometry and dimensional accuracy are required.

Related standards

Typical related documents include earlier national versions (GOST 2590-88), companion GOSTs for other bar shapes (e.g., GOST 2591 for square bars, GOST 2879 for hexagonal bars), and international standards addressing hot‑rolled round bar dimensions such as EN 10060:2003. Some national standards (e.g., Ukraine’s DSTU 4738:2007) were aligned with GOST 2590-2006.
