General Information
Ti 834 possesses the highest temperature capability of any commercial titanium alloy (up to 1112°F (600°C)) and is primarily used in aircraft engine applications. This “near alpha” alloy is weldable and possesses a fine grained alpha/beta microstructure that confers the best combination of tensile strength, fatigue and creep resistance. Furthermore, in comparison with other creep resistant Ti alloys, Ti 834 can be stress relieved at temperatures up to 1292°F (700°C).
