GOST 6713-2021 PDF

Full title and description

GOST 6713-2021 — "Прокат из конструкционной стали для мостостроения. Технические условия" (English: "Structural rolled stock for bridge building. Specifications"). The standard establishes technical requirements, classification, mechanical properties, testing and acceptance rules for structural rolled steel products intended for bridge construction.

Abstract

GOST 6713-2021 is an intergovernmental (Межгосударственный) standard that specifies types, grades and delivery conditions of rolled structural steel for bridges (thick plate, wide universal, section and shaped rolled products, strip and section rolled stock), classifies strength levels and impact-test categories, and sets requirements for sampling, mechanical and technological tests, surface quality, marking and accompanying documentation. It replaces earlier national versions and harmonizes referenced test methods and normative links.

Scope

The standard applies to structural rolled steel products intended for bridge construction, covering product types (thick plate, wide universal plate, section and shaped rolled products, strip and bar), strength classes (for example С325, С345, С390 as typical classes indicated in the standard), categories for impact testing (categories 1, 2, 3), and permissible supply conditions (hot-rolled, thermally treated, thermomechanically processed, and specified heat treatments). It also sets surface-quality requirements, testing methods to be used or referenced, sampling rules, and requirements for marking and documentation accompanying deliveries.

Key topics and requirements

• Classification of rolled products by type (thick plate, wide universal plate, section, shaped, strip, and bar) and by strength class.
• Mechanical-property limits for tensile strength, yield, elongation and reduction of area for specified grades (examples: classes С325, С345, С390 are treated with their minimum properties).
• Categories of impact testing and rules for Charpy or equivalent impact tests depending on service conditions and temperature class.
• Permitted supply conditions: hot-rolled (without heat treatment), thermally treated (annealed, normalized, quenched and tempered, etc.) and thermomechanically processed states.
• Surface quality criteria (prohibitions on laps, through cracks, heavy scale, delaminations, blisters, folds, cracks and other defects that could impair performance).
• Sampling, test methods and acceptance rules — references to national GOST test methods (chemical analysis, tensile tests including thickness-direction tests, impact testing, ultrasonic testing requirements, etc.).
• Documentation and marking requirements: delivery must be accompanied by quality certificates (form 3.1 or equivalent) including test results and heat-treatment/inspection notes.

Typical use and users

Primary users include bridge and structural engineers, steel manufacturers and mills producing rolled sections for bridge works, metal fabricators and constructors, procurement and quality-control specialists in construction and infrastructure projects, and regulatory/standards bodies ensuring compliance with bridge-material requirements. The standard is used to specify material acceptance criteria in tender and design documentation for bridge projects.

Related standards

GOST 6713-2021 replaces or updates previous national editions (e.g., GOST 6713-91). It references many test- and product-related standards such as (non-exhaustive): GOST 28870 (tensile testing in thickness direction), GOST 28473 (chemical analysis methods), GOST 30456 (impact testing methods), GOST 7564 (sampling rules), GOST 7566 (quality documentation), and a range of ГОСТ standards for steel grades and production. Users should verify the status of referenced standards when applying GOST 6713-2021.
