GOST 19807-91 PDF

Full title and description

GOST 19807-91 — "Wrought titanium and titanium alloys. Grades." Establishes the approved grades (markings) and chemical-composition limits for wrought (deformable) titanium and titanium alloys intended for manufacture of semi‑finished products and ingots.

Abstract

This interstate (GOST) standard defines the designations and chemical composition limits for commercial titanium and titanium alloys used for sheets, strips, plates, rods, profiles, tubes, forgings and other semi‑finished products produced by deformation (cold/hot working), and it specifies certain special provisions for particular grades (for example VT1‑00, VT1‑0, VT14 and others). The standard is mandatory where applied and includes later Amendment No.1.

General information

• Publication date: Introduced 01 July 1992 (designation 19807-91).
• Publisher: Originally developed under the USSR Ministry of Aviation Industry and approved by the USSR Committee for Standardization and Metrology; maintained/issued in the Russian Federation via Rosstandart (with Amendment No.1 introduced by Rosstandart).
• ICS / categories: Metallurgy — Non‑ferrous metals; Titanium and titanium alloys (ICS 77.120.50).
• Edition / version: GOST 19807-91 (original 1991 designation; entry into force 01.07.1992) with Amendment No.1 (reissue/amendment adopted in 2011 and introduced in Russia 01.07.2012).
• Number of pages: Commonly listed as 9 pages in Russian-language distributions; some vendor listings for translated/extracted versions show shorter page counts (e.g., 6 pages) depending on format.

Scope

The standard applies to commercially produced wrought (deformable) titanium and titanium alloys and sets the official grade (marking) designations and maximum/minimum mass‑fraction limits for alloying and impurity elements (Al, V, Mo, Zr, Sn, Fe, Si, O, N, H, C, etc.). It covers material intended for semi‑finished products (sheet, strip, foil, plate, bar, rod, profile, tube, forgings, stamped blanks) and ingots; hydrogen content for ingots and special composition limits for individual grades are specified.

Key topics and requirements

• Definition of grade/marking system for common titanium and titanium alloys used in deformation‑processed products (VT‑series, OT‑series, PT‑series, AT, etc.).
• Chemical‑composition limits for major alloying elements and impurities (Al, V, Mo, Zr, Sn, Fe, Si, O, N, H, C) for each grade.
• Special provisos for certain grades (for example: maximum Al in VT1‑00 and VT1‑0; Al range requirements for VT14 rolled products).
• Permitted partial substitution rules (e.g., limited substitution of molybdenum by tungsten) and combined impurity limits (Cu+Ni, Cr+Mn, etc.).
• Requirements apply to semi‑finished forms and ingots; hydrogen content noted specifically for ingots.

Typical use and users

Used by metallurgists, materials engineers, producers and suppliers of titanium semi‑finished products, purchasing/specification engineers in aerospace and aviation (original developer: Ministry of Aviation Industry), industrial manufacturers (chemical processing, power, marine), and quality/certification laboratories to ensure material grade and composition conformity. Typical applications include structural and corrosion‑resistant components, heat‑exchanger tubing, forgings and formed parts where specific titanium grades are required.

Related standards

Replaces earlier GOST 19807‑74; relates to other GOSTs covering titanium products and product‑specific requirements (e.g., standards for pipes, forgings, testing and chemical analysis). Internationally comparable specifications include ASTM/ASME standards for wrought titanium products (for example ASTM B265 for titanium sheet/plate/foil, ASTM B348 for bars and billets, and other ASTM/ISO/EN specs for titanium products and implant grades). Users commonly reference these alongside GOST 19807‑91 when mapping grades between systems.

FAQ

Q: What is this standard?

A: GOST 19807-91 is the interstate (GOST) standard that defines grades (markings) and chemical composition limits for wrought (deformable) titanium and titanium alloys used to make semi‑finished products and ingots.

Q: What does it cover?

A: It covers the list of approved grades and the permissible mass fractions of alloying elements and impurities for each grade, plus a number of special provisions for particular alloys and product forms (e.g., limits for aluminum in VT1‑00/VT1‑0, Al range for VT14 rolled products).

Q: Who typically uses it?

A: Producers and suppliers of titanium semi‑finished products, materials and quality engineers, certification/testing laboratories, and end‑users in aerospace, industrial manufacturing, chemical process equipment and other sectors where specific titanium grades are specified.

Q: Is it current or superseded?

A: The standard is listed as active/valid and has at least one later amendment (Amendment No.1 adopted 2011 and introduced in Russia from 01.07.2012). Users should confirm the latest national/regulatory status and any additional amendments or replacement standards before using it for procurement or certification.

Q: Is it part of a series?

A: It is one of a set of GOST and interstate standards covering titanium and titanium products (chemical analysis, product‑specific specifications, testing methods). It replaced GOST 19807‑74 and is related to other GOSTs that govern titanium product forms and quality requirements.

Q: What are the key keywords?

A: Titanium, titanium alloys, wrought, grades, chemical composition, semi‑finished products, ingots, VT‑series, GOST.
