VT20-2sv (ВТ20-2СВ)
VT20-2SV Titanium Alloy: A High-Performance Solution for Aerospace and Industrial Applications
VT20-2SV Tatinium, also known by its Russian designation ВТ20-2СВ, is a high-performance α+β titanium alloy that combines exceptional strength, fatigue resistance, and corrosion protection, making it a go-to choice for demanding aerospace, defense, and industrial applications. Its unique properties and versatility have made it a critical material in industries where both high strength and reliability under extreme conditions are essential.
What is VT20-2SV Titanium Alloy?
What is VT20-2SV Titanium Alloy?
VT20-2SV Tatinium, also known as ВТ20-2СВ, is a high-strength, heat-treatable α+β titanium alloy primarily used in demanding industries such as aerospace, defense, and marine engineering. This alloy is specifically designed to withstand high-stress environments, providing exceptional mechanical properties including superior strength, fatigue resistance, and corrosion protection.
It belongs to the system of titanium alloys designated under Russian / CIS standards (GOST / OST) and is often used where higher alloying is needed relative to simpler wrought titanium types.
Because of higher alloying, workability (forming, welding large sections, machining) may be more challenging than simpler Ti alloys. Available mechanical data is a bit limited (especially for large cross-section plates, heavy forgings) for this exact grade—most data is wire form.
