GOST 4543-2016 PDF

Full title and description

GOST 4543-2016 — "Metal products from structural alloy steel. Specifications" (Russian: Металлопродукция из конструкционной легированной стали. Технические условия). The standard defines technical conditions and product requirements for structural alloy (alloyed) steels used for rolled and forged metal products intended for heat-treated conditions.

Abstract

GOST 4543-2016 establishes specification requirements for structural alloy steels and for finished metal products produced from those steels (hot-rolled and forged stock, calibrated sections and products with specified surface finish) including chemical composition, mechanical properties, heat treatment, dimensional tolerances, testing and acceptance, marking and packing. It updates and replaces the earlier GOST 4543-71.

General information

• Status: Active / adopted as an interstate (GOST) standard; replaces GOST 4543-71.
• Publication date: Designation year 2016; published/entered into force (commercial publication) 1 October 2017 (commonly cited publication date).
• Publisher: Issued as a GOST (interstate) technical standard — published and distributed via national standard bodies and commercial standards publishers (national adoption/registration visible in national catalogs).
• ICS / categories: Metallurgy; classification entries commonly given as 77.140.10 and related metallurgy subclassifications for steel products.
• Edition / version: GOST 4543-2016 (current edition replacing the 1971 edition GOST 4543-71).
• Number of pages: Approximately 54 pages (standard commercial publications list 54 pages).

Scope

This standard covers technical specifications for metal products made from structural alloy (legiruyemaya konstruktsionnaya) steels: typical product forms include hot‑rolled and forged bars, rods, sections and similar stock intended to be supplied in heat‑treated (normalized, quenched and tempered, etc.) conditions. The document sets requirements for chemical composition and alloying, mechanical properties after specified heat treatment, dimensional and surface requirements, inspection and testing methods, marking and packaging, and acceptance criteria for delivery. It is intended to be used by producers, suppliers and consumers of alloyed structural steel products.

Key topics and requirements

• Specification of permissible chemical composition ranges for alloying elements and impurity limits (ensures grade traceability).
• Required mechanical properties (yield strength, tensile strength, elongation, impact toughness where applicable) after specified heat treatments.
• Designated product forms and dimensional/tolerance tables for bars, rods and standard sections; surface finish/quality designations.
• Heat treatment regimes and conditions for normalized, quenched-and-tempered, annealed states where applicable.
• Sampling, testing and inspection procedures (chemical analysis, mechanical tests, non-destructive testing where required) and acceptance criteria.
• Marking, packing and documentation requirements for delivery (traceability, certificates of conformity/test reports).
• Reference to related normative documents and mandatory national/regional registration/adoption rules for interstate standards.

Typical use and users

Used by steel mills and foundries producing alloy structural steels, metal processors and distributors, procurement and quality departments in manufacturing (machinery, construction, heavy equipment), testing and certification laboratories, design engineers specifying material grades, and regulatory/national standards offices implementing GOST-based requirements. The standard supports product specification, acceptance testing and supplier quality control.

Related standards

Directly supersedes GOST 4543-71. It is typically used alongside other GOST/EASC standards that specify testing methods, heat treatment procedures, chemical analysis methods and product marking/packaging rules; national adoption documents and technical regulations of member states may reference it. Commercial copies and translations are available from standards publishers.
