GOST 7417-75 PDF

Full title and description

GOST 7417-75 — "Calibrated round steel. Dimensions" (Сталь калиброванная круглая. Сортамент). The standard specifies the assortment (sizes and dimensional tolerances), mass per metre and related dimensional data for calibrated (cold-drawn or cold-rolled) round steel bars.

Abstract

Interstate (GOST) standard establishing the size range, limit deviations (tolerance classes), sectional areas and nominal masses for calibrated round steel with nominal diameters typically from about 3 mm up to 100 mm. It was prepared and adopted in the mid-1970s and has been published in standard catalogs and collections; several later catalog reprints and editorial notes record amendments.

General information

• Status: In force / active in standard collections (listed as действующий / active in multiple catalogues and e-shops).
• Publication date: Original designation 7417-75 (adopted 1975); entry into force/catalogue date commonly recorded as 01 January 1976.
• Publisher: State standards authority (Gosstandart / Межгосударственный стандарт — adopted by the State Committee for Standards of the USSR / Interstate standard system).
• ICS / categories: Metallurgy / rolled and forged steel products — classification codes reported as OKP/ICS area 77.140.60 (group В32).
• Edition / version: Original issue 1975 (GOST 7417-75); later catalog reprints and amendments noted (amendments recorded in IUS entries 1987 and 1989; reissue noted in 2003 collections).
• Number of pages: Commonly listed as 5 pages in major catalog records; some vendor/catalog copies show small variations (catalog entries report 5–8 pages depending on formatting).

Scope

Applies to calibrated round steel of circular cross-section produced by cold drawing or cold rolling, with nominal diameters typically in the range from approximately 3 mm up to 100 mm. The standard defines diameter series, corresponding limit deviations (tolerance classes such as h9, h10, h11, h12), cross‑sectional areas and nominal linear mass values used for ordering, manufacturing and inspection.

Key topics and requirements

• Nominal diameter series for calibrated round bars (typical range 3–100 mm) and associated tables of dimensions and masses.
• Limit deviations / tolerance classes (h9–h12) for diameters and requirements for permissible size deviations.
• Reference to steel grades and technical requirements that are established by corresponding material standards (i.e., specific steel grades are set by other GOSTs and normative documents used together with this assortment standard).
• Mass per metre, cross-sectional area tables and guidance for marking/identification of calibrated round bars for commercial and engineering use.
• Notes on amendments and historical reprints (catalog amendments IUS entries 1987 and 1989 noted in bibliographic records).

Typical use and users

Used by steel producers, metal stockists and distributors, procurement and quality departments in manufacturing (machining, cold forming, fastener and component production), design engineers who select standard bar sizes, and testing/inspection laboratories that verify dimensional conformity to assortment tolerances. Suppliers reference this GOST when offering calibrated round bars for mechanical and structural applications.

Related standards

Commonly used together with other metallurgical and product standards such as GOST 2590 / GOST 2591 (hot-rolled round bars and tolerances), GOST 1050 (steel grades), GOST 10702 (fine structural steels for cold extrusion/upsetting) and predecessor editions (e.g., GOST 7417-57). Catalog entries and standards indexes list these related documents as cross-references.

FAQ

Q: What is this standard?

A: An interstate GOST standard that specifies the assortment (size series), limit deviations (tolerances), sectional areas and nominal masses for calibrated round steel (cold-drawn or cold-rolled round bars).

Q: What does it cover?

A: Dimensional requirements for calibrated round bars (nominal diameters, tolerance classes such as h9–h12), tables of cross‑sectional area and mass per metre, and related ordering/assortment information for steel suppliers and users.

Q: Who typically uses it?

A: Steel mills, metal stockists and distributors, procurement and quality control specialists, machining and cold-forming manufacturers, and design engineers who need standardized bar sizes and tolerances.

Q: Is it current or superseded?

A: Bibliographic records and commercial catalogues list GOST 7417-75 as active (in force) in standard collections; it was adopted in 1975 (catalogue entry from 01.01.1976) and later included in reprints/collections with noted amendments. Users should check the official national standards body or current national catalogues for the latest legal status before relying on it for regulatory compliance.

Q: Is it part of a series?

A: Yes — it belongs to the family of GOSTs covering steel assortments and rolled product dimensions (other related GOSTs include earlier and parallel assortment standards and material specifications such as GOST 7417-57, GOST 1050, GOST 2590/2591 and GOST 10702).

Q: What are the key keywords?

A: Calibrated round steel; round bar; dimensions; tolerance classes (h9–h12); mass per metre; ассортимент; ГОСТ.
