characteristic
High-grade titanium rolling is considered the most popular among other types of titanium semi-finished products. A wire, a circle, a rod of a series FROM have a pseudo-structure of low heat resistance, but good manufacturability. Heat resistance, creep rate depend on the rate of cooling. Optimal is considered cooling with an intermediate speed between the furnace in water cooling. The rolling of the OT series is well welded by any type of welding.

Titanium semi-finished products exhibit deformation anisotropy. The effect of strengthening the alloy depends on alloy doping. The hardening factor is 1.18 in pure titanium and increases to 1.32 in complex alloys. Mark OT4−0 has a hardening factor of 1.23.
limitations
High labor intensity of production. Hot titanium reacts actively with atmospheric gases. Therefore, it melts only in an environment of inert gases or in a vacuum, Titanium brand OT does not differ high strength and has a tendency to hydrogen embrittlement.
Application of
Structural advantages, corrosion resistance, minimum coefficient of thermal expansion, ductility and low ud. The titanium weight of the OT series makes it expedient to use it in the manufacture of ship pumps, parts of heat exchanging equipment, spring valves, connecting rods, crank and cam shafts, clutch parts, fastening fittings. Alloys of titanium allow to reduce the load on mobile units by 30%, significantly increasing their durability and reliability.
