Technical characteristics

Description Identification
A grade of titanium alloy: AT3
Alloy classification: Titanium deformable alloy
Industrial usage of alloy: Manufacture of semi-finished products (sheets, strips, foils, plates, bars, pipes, ingots, forgings, sections, stamping bars) by a deformation method

Percentage composition of alloy according to GOST 19807 -91

Al N H Ti Si C Fe Cr O Residual elements
2 — 3.5 ≤0.05 ≤0,008 94.65 — 97.1 0.2 — 0.4 ≤0.1 0.2 — 0.5 0.2 — 0.5 up to 0.15 others 0,3

Alloying increases strength characteristics and corrosion resistance of titanium 2−3 times as much. One of the main alloying elements is aluminium. It is present in almost all types of titanium.

Identification Description
weldable without imits welding is done without final heat treating or previous heating;
limitedly weldable welding is possible at heating to 100−120°С and last heat treating;
hardly weldable in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treating (annealing) after welding;


Titanium and its alloys are not inferior to steel by strength, but they are twice lighter. They differ with heat resistance and low heat conduction. Advantages of titanium are very promising in technical fields that require high strength-to-density ratio, heat resistance in combination with high corrosion resistance. Food, chemical industries, aviation, rocket-building, shipbuilding, motor vehicle mechanical engineering cannot do without titanium. Extraordinary characteristics of this metal in the capacity of a structural material are of the utmost interest in spacecraft engineering.
