GOST 1050-2013 PDF

Full title and description

GOST 1050-2013 — "Metal products from non-alloyed structural quality and special steels. General specifications" (Russian: «Металлопродукция из нелегированных конструкционных, качественных и специальных сталей. Общие технические условия»). The standard establishes general technical requirements, chemical composition and mechanical-property rules, delivery conditions, marking and testing methods for hot-rolled, forged, calibrated and specially finished products of non‑alloy carbon and special steels.

Abstract

GOST 1050-2013 is an interstate (EASC) standard that consolidates and modernizes requirements for non‑alloy structural, quality and certain special steel grades used in industry. It defines product forms (bars, blooms, slabs, rolled and forged stock, forgings, sheet and other items), limits on chemical elements, mechanical properties, testing and inspection procedures, and rules for marking and delivery. The standard replaced earlier national GOST texts for many grades and provides unified technical conditions for suppliers and manufacturers across member states.

General information

• Status: Current / in force (interstate standard adopted for national application in the Russian Federation).
• Publication date: Document designation year 2013; adopted by interstate bodies in December 2013 and introduced as a national standard in the Russian Federation from 1 January 2015.
• Publisher: Interstate Council for Standardization, Metrology and Certification (EASC) / published via standardization bodies; national registration and implementation administered by the Federal Agency on Technical Regulating and Metrology (Rosstandart) in Russia.
• ICS / categories: 77.140.45; 77.140.60 (metallurgy — steels and ferroalloys / rolled and forged products).
• Edition / version: Edition designated by year 2013 (GOST 1050‑2013).
• Number of pages: Typically published as a 36‑page document (electronic/printed formats sold by standards publishers).

Scope

The standard applies to non‑alloy (carbon) structural, quality and certain special steels in a range of product forms including hot-rolled and forged stock, calibrated bars, forgings and sheets. It sets out requirements for chemical composition limits, mechanical properties, permissible deviations of form and size, surface quality and special finishes, rules for heat treatment and marking, and the types and methods of tests (chemical analysis, mechanical testing, non‑destructive inspection and others) required for conformity. It is intended for use by producers, processors, testing laboratories and procuring organizations across member states.

Key topics and requirements

• Definition of steel grades covered (wide range of quality carbon and some special steels) and classification of product forms (bars, blooms, slabs, sheet, forgings, etc.).
• Limits on chemical composition for each grade (C, Si, Mn, P, S and trace elements) and tolerances for impurities.
• Mechanical property requirements and test methods (tensile, yield, elongation, hardness, impact where specified).
• Requirements for form, dimensional tolerances and surface finish; permitted deviations and acceptance criteria.
• Rules for sampling and chemical/mechanical testing — spectrographic, XRF and other referenced national test methods.
• Marking, certification and delivery conditions (documentation, lot marking and supplier responsibilities).

Typical use and users

Primary users are steel producers, rolling mills, forging shops, metal‑working manufacturers, procurement and quality departments in machine‑building, automotive, rail, oil & gas, and construction sectors, as well as testing laboratories and conformity assessment bodies. Engineers and materials specialists use the standard to select appropriate steel grades and to verify compliance of supplied metal products with contractual and regulatory requirements.

Related standards

GOST 1050-2013 replaces (fully or in part for many grades) earlier national standards such as GOST 1050-88 and parts of GOST 4543-71. It references numerous test and measurement standards for chemical analysis and non‑destructive examination (for example, national GOST methods for spectrographic analysis, XRF, magnetic testing and dimensional measurement). Users should consult the normative references listed in the standard when applying specific test procedures.

FAQ

Q: What is this standard?

A: GOST 1050-2013 is an interstate standard that specifies general technical requirements for metal products made from non‑alloy structural, quality and certain special steels, covering composition, properties, testing, marking and delivery conditions.

Q: What does it cover?

A: It covers hot‑rolled, forged, calibrated and specially finished steel products (bars, blooms, slabs, forgings, sheet, etc.), defining limits for chemical elements, mechanical properties, dimensional and surface requirements, sampling and test methods, and supplier documentation.

Q: Who typically uses it?

A: Steelmakers, rolling and forging manufacturers, metal fabricators, materials and quality engineers, procurement specialists, and testing laboratories use the standard to specify and verify steel products.

Q: Is it current or superseded?

A: The 2013 edition (GOST 1050-2013) is the current interstate edition and was introduced for national application in Russia effective 1 January 2015; it replaced earlier GOST texts for many steel grades. Users should check national catalogs and amendment bulletins for any later changes or amendments before use.

Q: Is it part of a series?

A: GOST 1050-2013 is a general specification in a family of metallurgy standards and works together with more specific GOST/GOST R documents and test‑method standards referenced in its normative references; it is not a single‑grade specification but a general technical framework for many non‑alloy steel grades.
