GOST 19281-89 PDF

Full title and description

GOST 19281-89 — "Прокат из стали повышенной прочности. Общие технические условия" / "Rolled steel with increased strength. General specifications". The standard sets general technical requirements, classification and acceptance rules for hot-rolled high-strength rolled steel (heavy plate, wide-strip, universal, shaped and section products, and bent profiles) and includes referenced chemical-composition and mechanical-property requirements for grades intended for welded, bolted or riveted structures.

Abstract

This interstate (GOST) standard establishes general specifications for rolled steel of increased strength: definitions, classification by strength classes, dimensional and surface requirements, mechanical and chemical property limits, acceptance and testing rules (including batch acceptance), and special provisions for weldability and delivered product marking. It was adopted in 1989 with an amendment and was used to harmonize national practice with a set of related ISO documents cited in the text.

Scope

GOST 19281-89 applies to hot-rolled rolled-steel products of increased strength — including thick plate, wide-strip (universal), shaped and section rolled products, and bent profiles — intended primarily for welded, riveted or bolted structures and typically delivered without additional heat treatment. In respect of regulated chemical composition the standard also covers melts and semi-finished forms (ingots, blooms, slabs), thin sheet, forgings and stampings where referenced. The standard includes classification by strength classes and prescribes acceptance, testing and marking provisions appropriate for structural applications.

Key topics and requirements

• Classification of rolled products by strength classes (examples in the standard include classes such as 295, 315, 325, 345, 355, 375, 390, 440 and associated mechanical requirements).
• Mechanical-property limits (yield and tensile strength, elongation) specified by strength class and by product type (plate, strip, section, etc.).
• Chemical-composition limits and rules for products with regulated composition; provisions for ladle analysis and allowable deviations.
• Acceptance rules: batch (party) acceptance, party composition requirements, maximum party mass (commonly cited as not to exceed 350 t) and requirements when continuous-casting or single-heat origin is important.
• Surface quality, dimensional tolerances and edge/cut conditions referred to related GOSTs (for example, surface/dimensions per GOST 14637, sectional dimensions per GOST 535, and sizing references to GOST 19903 where applicable).
• Weldability guidance, carbon-equivalent calculation and additional properties that can be specified at the purchaser’s request.
• References and harmonization with relevant ISO documents (ISO 4950 series, ISO 4951, ISO 4995/4996, ISO 5952 noted in the document header).

Typical use and users

Used by steel producers and rolling mills to specify and certify high-strength rolled steel; by fabricators and structural engineers for material selection in welded, bolted or riveted structures; by procurement and quality-control laboratories for acceptance testing, sampling and verification; and by standards/technical libraries as a reference for product specification and contractual documentation.

Related standards

Referenced and related documents include the later replacement standard GOST 19281-2014 (which updates and supersedes GOST 19281-89), and numerous GOSTs cited in the text such as GOST 19903 (hot-rolled steel sheet), GOST 535 (sectional rolled products), GOST 7566 (acceptance rules), and others; the standard also aligns with several ISO documents (ISO 4950 series, ISO 4951, ISO 4995/4996, ISO 5952) listed in the original header.

FAQ

Q: What is this standard?

A: GOST 19281-89 is an interstate technical standard titled "Rolled steel with increased strength. General specifications" that established general requirements for hot-rolled high-strength rolled steel products.

Q: What does it cover?

A: It covers classification by strength class, mechanical and chemical requirements, dimensional and surface requirements, acceptance and testing rules (party acceptance, sampling), weldability guidance and references to related GOST/ISO test and measurement methods.

Q: Who typically uses it?

A: Steel manufacturers, rolling mills, material purchasers, structural designers and fabricators, and testing/quality laboratories use the standard for specifying and verifying high-strength rolled steel for structural applications.

Q: Is it current or superseded?

A: The 1989 edition was subsequently superseded by a 2014 revision — GOST 19281-2014 — which serves as the replacing (updated) standard; users should refer to the 2014 edition for the most current national requirements.
