Full title and description

GOST 2284-79 — Cold-rolled carbon structural steel strip. Technical specifications. This interstate (GOST) standard defines classification, sizes, steel grades, mechanical properties, surface and edge types, tolerances and acceptance rules for cold‑rolled carbon structural steel strip (tape) intended for manufacture of machine parts and structural components.

Abstract

GOST 2284-79 (introduced 1 January 1980) establishes technical conditions for cold‑rolled strips of carbon structural steels: classification by accuracy and surface quality, nominal thickness and width ranges, permitted steel grades (references to GOST 1050, GOST 803 and others), mechanical-property requirements for annealed and work‑hardened conditions, and rules for testing, marking and acceptance. The edition includes Amendments No.1–4 issued between 1981 and 1990.

General information

• Status: Interstate GOST standard (introduced 1979, brought into force 1 January 1980); edition with amendments No.1–4 (1981–1990).
• Publication date: 1980-01-01 (date of introduction into force).
• Publisher: Approved by the State Committee for Standards of the USSR; developed and introduced by the Ministry of Ferrous Metallurgy of the USSR.
• ICS / categories: Metal products / cold‑rolled strip — classified under group B34 and OKP 12 3100 in available records; corresponds in mechanical‑property intent to ISO 4960‑86.
• Edition / version: GOST 2284-79 (original 1979/1980) with Amendments No.1 (1981), No.2 (Feb 1986), No.3 (Aug 1986) and No.4 (July 1990).
• Number of pages: 10 pages (standard text / typical PDF reproduction).

Scope

The standard applies to cold‑rolled tape (strip) of quality carbon structural steels intended for manufacture of machine parts and structural elements. It specifies allowable thickness and width ranges, steel grades permitted for strip production, distinctions for accuracy and surface finish, mechanical properties for annealed and work‑hardened conditions, and inspection/acceptance procedures. Tabled values cover a wide set of nominal thicknesses (from about 0.10 mm up to 4.00 mm and beyond in specific ranges) and extensive width options.

Key topics and requirements

• Classification and assortment: accuracy classes (normal, increased, high precision), surface quality categories, edge types (cut or mill), and processing states (annealed, work‑hardened).
• Dimensional ranges and tolerances: nominal thickness and width tables with permitted deviations and matching width/ thickness combinations.
• Permitted steel grades: references to GOST 1050 grades (15–60, etc.), GOST 14959 grades (65,70) and specific alloys such as 18JUA per GOST 803.
• Mechanical properties: tensile strength and minimum elongation values for annealed and work‑hardened strips, with separate tables for ordinary and high‑quality annealed conditions.
• Surface, edge, and finish requirements: surface appearance categories, permissible non‑operational layer depths, and edge condition specifications.
• Testing, marking and acceptance: sampling and test procedures, conformity assessment and marking rules as defined in the standard text.

Typical use and users

Primary users include steel mills and cold‑rolling manufacturers producing strip/tape, component manufacturers (stamping, springs, small machine parts), fastener producers, and engineering designers specifying raw strip for fabrication of structural and mechanical parts. Standards/quality departments and procurement teams use the document to verify material properties and acceptance criteria.

Related standards

GOST 2284-79 references and is used alongside other material and testing standards such as GOST 1050 (steel grades), GOST 803 (specific alloy grades), and other GOSTs cited in its normative references; it is noted to correspond to ISO 4960‑86 for certain mechanical‑property aspects and it superseded GOST 2284‑69.

A: GOST 2284-79 is an interstate technical standard that specifies requirements for cold‑rolled carbon structural steel strip (tape), including dimensions, grades, mechanical properties, surface and edge conditions, and acceptance rules.

Q: What does it cover?

A: It covers classification, allowable nominal thickness and width ranges, steel grades permitted for strip manufacture, mechanical‑property tables for annealed and work‑hardened states, surface/edge quality categories, testing and marking procedures, and related normative references.

Q: Who typically uses it?

A: Steel producers, cold‑rolling mills, manufacturers of stamped and formed metal parts, quality and procurement engineers, and standards bodies use the document to specify and verify strip material for mechanical and structural applications.

Q: Is it current or superseded?

A: GOST 2284‑79 was introduced into force on 1 January 1980 and includes several later amendments (through 1990). Records show it replaced an earlier GOST 2284‑69. For whether it remains the applicable national/regional standard today or has been fully superseded in a specific country, consult the national standards registry or current GOST/R listings.

Q: Is it part of a series?

A: It belongs to the family of GOST standards regulating steel grades, flat products and testing (cross‑referenced with GOST 1050, GOST 803, and other related GOSTs) and is listed alongside other cold‑rolled and flat product standards in metal‑product groups.
