ot4 is a titanium-aluminum-manganese wrought alloy. Under the material designation ot4-1, one understands:

• OT - experimental titanium;
• 4-1 - test number.

The wrought alloy consists of approx. 93–98% titanium, approx. 1–2.5% aluminum, and approx. 0.7–2% manganese. It can be formed well both cold and hot. In addition, the material is characterized by excellent weldability with all standard welding methods and good corrosion resistance. However, ot4 has relatively low strength and tends to hydrogen embrittlement.

At Evek GmbH, ot4-1 is offered at a good price. Our products are characterized by high quality. You buy GOST steels safely and reliably.

In the annealed state, ot4 is mainly used in aircraft construction for the production of load-bearing structures. In addition, it is used to manufacture thin-walled components with difficult shapes, which are operated over a longer period at temperatures of 300 °C (max. 30,000 operating hours) to 350 °C (max. 2,000 operating hours).

ot4-1 has the following features:

• good cold and hot formability;
• excellent weldability;
• good corrosion resistance;
• rather low strength;
• tends to hydrogen embrittlement.
