GOST 4761-91 PDF

Full title and description

GOST 4761-91 — "Ферротитан. Технические требования и условия поставки" (Ferrotitanium. Specification and conditions of delivery). The standard establishes technical requirements, chemical composition limits, delivery, packaging and inspection rules for ferrotitanium supplied to steelmaking and foundry industries.

Abstract

GOST 4761-91 adapts ISO 5454:1980 for interstate (former USSR) application and sets mandatory requirements for the manufacture, acceptance tests, marking and delivery of ferrotitanium grades intended as alloying and deoxidizing ferroalloys in steel and foundry practice. It defines composition ranges, sampling and testing procedures, packing, and documentation required at delivery.

Key bibliographic and status data above are taken from official-text repositories and standard collections.

Scope

The standard applies to ferrotitanium produced by reduction or remelting and intended for supply to steel-melting and foundry plants. It covers definitions, grade designation, required chemical composition limits, technical requirements (including limits for impurities), methods and rules for sampling and chemical analysis, requirements for testing and acceptance, marking, packing and delivery documentation.

Key topics and requirements

• Definition of ferrotitanium (Fe–Ti alloy) and permissible titanium content range (typical Ti content classes covered by the standard; ferrotitanium is defined with Ti content from about 20 % up to ~75 % by mass in the text).
• Chemical composition limits for major alloying elements and maximum admissible impurities (S, P, C and selected metallic elements), with specified acceptance criteria.
• Designation of grades and marking rules for delivered material.
• Requirements for sampling, sample preparation and chemical analysis methods (references to relevant GOST/ISO test methods).
• Conditions of delivery: packaging, packing units, documentation (delivery note, certificate of conformity or chemical analysis), and storage/transport recommendations.
• Reference to ISO 5454-80 as the international base standard and additional national requirements included in the GOST text.

These topics are summarized from the standard text and official annotations.

Typical use and users

Primary users are steelmakers, foundries, ferroalloy manufacturers, metal purchasing/procurement departments, quality-control and chemical laboratories, and standards/technical compliance specialists involved in alloy selection, acceptance testing and supply chain documentation for ferroalloys. The material is used as an alloying and deoxidizing agent in stainless, heat-resistant and specialty steels and in welding-electrode metallurgy.

Related standards

GOST 4761-91 is directly linked to ISO 5454-80 (Ferrotitanium) and replaces the earlier GOST 4761-80. It references a range of GOST methods for chemical analysis (for example the GOST 14250 series and other metallurgy testing standards) and sits within the ferroalloys cluster of standards (ICS 77.100). Related GOSTs include methods and specifications for ferroalloys such as ferrochromium and associated analytical methods.
