5. EDITION (July 2005), with Changes N 1, 2, 3, 4, 5, approved in November 1982, June 1986, June 1987, August 1990, March, 2004 (I & C 3−83, 9−86, 11−87, 11−90, 6−2004)


This standard applies to sheets of titanium and titanium alloys, designed for the needs of the national economy and exports.

(Changed edition, Rev. N 2).

1. ASSORTMENT

1.1. The leaves are divided as follows:

a) the quality of surface finish:

high finish, high finish — P, the usual finish — at no extra designation;

b) the deviation from flatness:

improved flatness — normal flatness, without additional symbols.

(Added, Rev. N 4).

1.1. The thickness of the sheets, limit deviations on thickness depending on thickness and width of sheets shall be as specified in table.1.

Notes:

1. Sheets of titanium grade VT1−0 with a thickness of 2.0 to 10.5 mm and a width of 1000 mm width is permitted to produce in excess of the nominal size is not more than 30 mm.

2. At the request of the consumer the sheets of alloy grade VT20 with thickness from 1.8 to 10.5 mm are made with a width of 1000 mm.


(Changed edition, Rev. N 1, 4, 5).

1.3. (Deleted, Rev. N 4).

1.4. Sheets of titanium and titanium alloy grades VT1−00, VT1−0, OT4−0, OT4−1 and OT4 with thickness up to 1.8 mm manufactured lengths with an interval of 50 mm in the range of lengths provided in the table.2.

Sheets of titanium and titanium alloy grades VT1−00, VT1−0, OT4−0, OT4−1 and OT4 with a thickness of 2.0 to 10.5 mm manufactured lengths with an interval of 100 mm in the range of lengths provided in the table.2.

(Changed edition, Rev. N 1, 4).

1.5. Limit deviations on width of sheets shall not exceed:

plus 10 mm — at length of sheets up to 1500 mm;

plus 15 mm — with a length of over 1,500 mm.

1.6. Maximum deviations along the length of the sheets must not exceed:

plus 20 mm — at length of sheets up to 2000 mm;

plus-25 mm — at length of sheets more than 2000 mm.

The theoretical mass of one meter length of the sheet is given in Annex 1 and calculated at a density of 4.50 g/cmГОСТ 22178-76 Листы из титана и титановых сплавов. Технические условия (с Изменениями N 1-5), which corresponds to the density of titanium grades VT1−00 and VT1−0.

To calculate the theoretical mass of leaves from other titanium alloys should use the conversion factors listed in Annex 2.

(Changed edition, Rev. N 3).

2. TECHNICAL REQUIREMENTS

2.1. Sheets are produced in accordance with the requirements of this standard for technological regulations approved in the prescribed manner.

(Added, Rev. N 1).

2.1. Chemical composition of sheets of titanium grades VT1−00, VT1−0 and titanium alloys OT4−1, OT4−0, OT4, VT5−1, VT6, VT6S, VT14, VT20 must meet the requirements of GOST 19807 or OST 1 90013*.
