1. This standard establishes grades of titanium and titanium deformable alloys intended for the production of semi-finished products (sheets, tapes, foil, strips, plates, rods, profiles, pipes, forgings and stamped blanks) by the deformation method, as well as ingots.
The requirements of this standard are mandatory.
2. The grades and chemical composition of titanium and titanium alloys must correspond to those given in the table.
The mass fraction of hydrogen is indicated for ingots.
3. In titanium grade VT1-00, the permitted mass fraction of aluminum is no more than 0.30%, in titanium grade VT1-0 - no more than 0.70%.
4. In flat rolled products made of VT14 alloy with a thickness of up to 10 mm, the mass fraction of aluminum should be 3.5-4.5%, and in other types of semi-finished products - 4.5-6.3%.
5. In the alloy grade VT3-1, intended for the production of blade stampings and blade blanks, the upper limit of the mass fraction of aluminum should be no more than 6.8%.
6. In the PT-3V alloy, the mass fraction of zirconium in total with other impurities should not exceed 0.30%.
7. In all alloys containing molybdenum as an alloying element, its partial replacement with tungsten in an amount of no more than 0.3% is permitted.
The total mass fraction of molybdenum and tungsten must not exceed the standards provided in the table for molybdenum.
8. In all alloys that do not contain chromium and manganese as alloying elements, the mass fraction of the latter should not exceed 0.15% (in total).
9. The mass fraction of copper and nickel in titanium and in all alloys must be no more than 0.10% (in total), including nickel no more than 0.08%.
10. The column "Amount of other impurities" includes the elements specified in paragraphs 8 and 9, as well as other elements listed in the table, but not regulated as impurities.

the note to the table shall be set out in a new version:
"Notes
1. The mass fraction of elements is maximum unless limits are specified.
2. The mass fraction of hydrogen is indicated in the regulatory documentation for specific types of semi-finished products."
The standard shall be supplemented with sections 11-14:
"11. For alloys of grades PT-1M, 3M, 2V, 5V, 14, 19, 27, 37, 40, it is allowed to introduce modifying chemical elements up to 0.003%. Alloys modified with boron are additionally marked with the index B. Boron is introduced into alloys in accordance with the calculated composition and its actual content is not determined.
12. In grade 5B alloy, the zirconium content together with other impurities should not exceed 0.3%.
13. In alloys of grades 3M and 19, the content of vanadium and tin is allowed to be no more than 0.15% (in total).
