GOST R 55374-2012 PDF

Full title and description

GOST R 55374-2012 — Rolled steel (alloyed structural rolled steel) for bridge building. General specifications. The standard establishes requirements for hot-rolled plates, wide flats, shaped rolled sections and bars of alloyed structural steels intended for manufacture of rail, road, combined, urban and pedestrian bridges (including northern climatic execution and seismicity up to 9 points), and specifies classification, chemical composition, mechanical properties, acceptance, testing and delivery conditions.

Abstract

This national Russian standard specifies general technical requirements for alloyed structural rolled steel used in bridge construction, including strength grades, permitted steel grades, dimensional assortment, mechanical and impact properties, sampling and test methods, marking, packing and storage. It is intended to ensure suitability of rolled steel products for load‑bearing bridge structures operating in specified climatic and seismic conditions.

Scope

The standard applies to hot‑rolled plate, wide flats (universal wide plate), shaped rolled sections and bars of alloyed structural steel intended for fabrication of load‑bearing bridge structures (rail, road, combined, urban and pedestrian bridges). It covers products for conventional northern climatic execution and for operation in areas with an estimated seismicity up to 9 points inclusive. The standard excludes drawbridge mechanisms. It also addresses cold‑formed profiles made from plates and thick plates of grade 09G2SD used as base layers in two‑layer rolling.

Key topics and requirements

• Classification of product types (plate, wide flats, bars, shaped sections) and permitted strength classes (S325, S345, S390) with associated steel grades (for example 09G2SD, 15KHSND, 10KHSND as indicated in the standard).
• Chemical composition limits and heat‑treatment/delivery conditions for each steel grade and strength class.
• Mechanical property requirements (tensile strength, yield, elongation) and conditional impact‑strength categories for various temperatures and delivery conditions.
• Sampling, specimen preparation and test methods referenced to national/ISO test methods (sampling, tensile, impact, spectral analysis and other normative references listed in the standard).
• Dimensional assortment, limit deviations, and permitted manufacture-by‑agreement sizes for plates, profiles and bars.
• Acceptance rules, marking, packing, transportation and storage requirements for rolled products intended for bridge work.
• Special conditions for northern climatic execution and seismic‑resistant applications (designated application limits such as seismicity up to 9 points).

Typical use and users

Primary users are steel producers and mills that manufacture hot‑rolled structural alloy products for the bridge industry; bridge designers and structural/civil engineers specifying material for bridge projects; procurement and quality departments of infrastructure contractors; testing laboratories performing mechanical and chemical verification; and regulatory bodies overseeing compliance with national construction and transport standards. Commercial suppliers of bridge plate and profiles reference the standard when listing product conformity.

Related standards

The standard normatively references a range of GOST and ISO test and product standards covering sampling, chemical analysis, tensile and impact tests, dimensional and assortment rules, and acceptance procedures — examples include GOST R 50424, GOST R 53845 (ISO 377), GOST R 54153, GOST 1497 (ISO 6892), and many other GOSTs governing ultrasonic testing, spectrographic/photoelectric analysis and product assortment. These related standards provide the referenced test methods and requirements used throughout GOST R 55374-2012.
