Description

Titanium VT1−0 is used: for the manufacture of semi-finished products (sheets, strips, foils, strips, plates, bars, rods, profiles, tubes, forgings and forged blanks) by the method of deformation, and also ingots; consumable electrode vacuum-arc remelting used as charge in the manufacture of shaped castings; longitudinally welded pipes for industrial pipelines, operating at conventional pressure PN (Pu) not more than 10 MPa and temperature 300 °C; products with high strength with sufficient ductility and toughness, high resistance to small plastic deformation, brittle and fatigue failure, used in mechanical engineering, instrument making and tool-making industry, products cryogenic equipment; welded structures and joints of equipment, working in conditions of radiation effects; cathodes matrices electrolysis baths; bellows, designed for use as delimiters environments, seal elements, the elastic elements and the elements of the power unit (actuator) in environments that do not cause corrosion of the material at the temperature from minus 50 °to plus 200 °C.

Note

The material of the low strength, and titanium VT1−0, containing more impurities than VT1−00, is more strength and less ductility. The strength properties of titanium can be increased by cold deformation but much reduced plastic properties. Reduced characteristics of plasticity are more pronounced than the increase of the strength characteristics, so that the cold deformation is not the best way to improve the properties of titanium. The disadvantages of titanium include high propensity to hydrogen embrittlement, the hydrogen content should not exceed 0.01% in titanium VT1−0.
