Technical characteristics

This alloy relates to deformable titanium alloys. It can be alloyed with aluminium or vanadium. It is easy weldable material. It is used for aircraft in bearing parts, production of large-size built-up and welded fragments of fuselage. It is intended to work under stress in a wide temperature range from 196 to 450 °C.

Heat treatment

Annealing temperature is 750−800°C for thin-walled pipes, sections. Cooling is performed in air or in furnace. Annealing of large parts is performed at t° of 760−800°C. It is cooled in a furnace. This approach prevents buckling of products. It allows avoiding partial thermohardening for small parts. In recent times, experts are inclined to believe that it is much better to increase an annealing temperature to 900−950°C. This leads to increase of toughness level and impact hardness. At that, it will keep plastic properties of a product due to a formation of mixed composition, if there is a large proportion of plate component. Such type of alloying allows increasing corrosion resistance level.


Identification Description
without limits
welding is done without further heat treatment or heating
limitedly weldable welding is possible at heating to 100−120°С and further 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
