SAE AMS4898C

This specification covers a titanium alloy in the form of sheet.

This sheet has been used typically for parts requiring high strength, toughness, and fatigue strength up to 750 \mDF (399 \mDC), but usage is not limited to such applications. The product an be super-plastically formed above 1500 \mDF (816 \mDC) and it can be aged after air cooling from the solution treatment or super-plastic forming temperature to increase the strength.

Certain processing procedures and service conditions may cause this sheet to become subject to stress-corrosion cracking; SAE ARP 982 recommends practices to minimize such conditions.
