ot4-1 is a titanium alloy containing aluminum and manganese. The designation ot4-1 stands for:
- OT – experimental titanium
- 4-1 – trial number
This alloy is composed of approximately 93-98% titanium, 1-2.5% aluminum, and 0.7-2% manganese. It is easy to form both hot and cold, offers excellent weldability with standard methods, and provides good corrosion resistance. However, ot4-1 has moderate strength and can be susceptible to hydrogen embrittlement.
Evek GmbH supplies ot4-1 at competitive prices, with a focus on high-quality products. Purchase GOST steels reliably and securely from us.
In its annealed state, ot4 is primarily used in the aerospace industry for load-bearing structures. It is also suitable for manufacturing thin-walled, complex-shaped components designed to operate at temperatures up to 300 °C (for a maximum of 30,000 hours) or 350 °C (for a maximum of 2,000 hours).
Key features of ot4-1 include:
- Good hot and cold formability
- Excellent weldability
- Good resistance to corrosion
- Moderate strength
- Susceptibility to hydrogen embrittlement
