GOST 22178-76 PDF

Full title and description

GOST 22178-76 — "Листы из титана и титановых сплавов. Технические условия" (English: "Titanium and titanium alloys — Sheets. Technical requirements"). The standard sets technical requirements for the manufacture, testing, acceptance, marking, packing and delivery of hot- and cold-rolled titanium sheets and foils intended for industrial and export use.

Abstract

GOST 22178-76 specifies permitted chemical compositions and mechanical properties, dimensional and surface quality requirements, sampling and test methods (tensile, bend, non‑flatness, hydrogen content, etc.), marking and documentation rules for sheets made of commercially pure titanium and titanium alloys. It provides acceptance criteria and references other GOST test and measurement norms.

General information

• Status: Active / in force with a sequence of amendments (standard maintained and periodically updated).
• Publication date: Approved 28 September 1976; put into effect 1 July 1978 (effective date commonly cited as 01.07.1978).
• Publisher: Originally approved by the State Committee for Standards of the USSR (Gosstandart) — developed by the Ministry of Aviation Industry; subsequently maintained/republished by national standard bodies (reissues and amendments).
• ICS / categories: ICS 77.150.50 (Products of titanium); classification group V53.
• Edition / version: Original designation ГОСТ 22178-76 with a series of amendments (Изм. N 1–N 6); last registered amendment entries noted in the public record through 2023.
• Number of pages: Varies by publisher/reissue (commonly reported in vendor/standards catalogs as about 16–20 pages depending on scanned/reissued edition).

Scope

The standard applies to rolled sheets and foils of titanium and titanium alloys intended for the national economy and export. It covers dimensions and tolerances (thickness, width, length), allowable surface condition and defect repair, chemical composition limits, mechanical property requirements (tensile strength, yield, elongation), heat treatment conditions where applicable, sampling rules and acceptance tests, and requirements for marking, packing and accompanying documentation. The document also cites referenced GOSTs for specific test and measurement methods.

Key topics and requirements

• Chemical composition limits for commercially pure titanium grades and common titanium alloys used in sheet form.
• Mechanical property requirements (tensile tests, yield/UTS, elongation) and shapes/sizes of test specimens.
• Surface quality, allowable defects, and permitted methods for defect removal/repair (grinding, scraping) and measurement of defect depth.
• Dimensional tolerances for thickness, width and length; flatness/non‑flatness measurement methods.
• Hydrogen content control and referenced methods (e.g., determination per referenced normative documents).
• Acceptance rules, sampling plans and required test reports/certificates supplied with shipments.
• Marking, packing and storage requirements appropriate for export and domestic delivery.

Typical use and users

Primary users are titanium producers, rolling mills, metal distributors, quality and inspection laboratories, and purchasers in aerospace, chemical process equipment, shipbuilding, instrumentation and other industries that require corrosion‑resistant, high‑strength, low‑density sheet materials. Regulatory and procurement departments referencing product specifications for supply contracts also use the standard.

Related standards

GOST 22178-76 includes references to other normative documents and testing standards (examples of referenced GOSTs include GOST 427 for measurement tools, GOST 1497‑84 for certain test methods, GOST 1760‑2014 and others). Implementers should consult the list of referenced standards in the standard text for full traceability of test and measurement procedures.
