SAE AMS4898 Revision D, January 1, 2014
Titanium Alloy, Sheet 6Al - 2Sn - 2Zr - 2Mo - 2Cr - 0.15Si Annealed
Description / Abstract:
Form
This specification covers a titanium alloy in the form of sheet in nominal thicknesses 0.016 through 0.1874 inch (0.41 through 4.760 mm).
Application
This sheet has been used typically for parts requiring high strength, toughness, and fatigue strength up to 750 °F (399 °C), but usage is not limited to such applications. The product can be superplastically formed above 1500 °F (816 °C) 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; ARP982 recommends practices to minimize such conditions.
