TIMETALŪ 834 HIGH STRENGTH, HIGH TEMPERATURE, CREEP RESISTANT ALLOY
Ti-5.8Al-4Sn-3.5Zr-0.7Nb-0.5Mo-0.35Si-0.06C

TIMETAL 834 is a near alpha alloy offering increased tensile strength and creep resistance up to 1110°F (600°C), together with improved fatigue strength when compared with TIMETALŪ 6242, TIMETAL 829 and TIMETAL 685. The alloy derives its properties from solid-solution strengthening, and heat treatment high in the alpha + beta phase field. It retains a good level of properties up to around 3 in (75mm) diameter, with small reductions in strength in larger sections. TIMETAL 834 has good forgeability and is weldable using all of the established titanium welding techniques. Major uses for TIMETAL 834 include rings, compressor discs and blades for aeroengines.
