AMS 4898 - Ti-6Al-2Sn-2Zr-2Mo-2Cr Titanium Alloy Bars, Billets, and Forgings
AMS 4898 is the SAE specification for Ti-6Al-2Sn-2Zr-2Mo-2Cr (Ti-6-2-2-2-2) titanium alloy bars, billets, and forgings. This alpha-beta alloy is designed for applications requiring higher strength and improved fracture toughness compared to standard 6Al-4V, particularly for forgings used in highly stressed aerospace structural and engine components.
Bars, billets, and forgings per AMS 4898 are used in high-strength aerospace structural fittings, military aircraft primary structure, and engine casings where 6Al-4V does not meet the strength or elevated-temperature capability requirements. The alloy can be heat treated to solution treated and aged condition for maximum strength or used in the annealed condition for better fracture toughness.
6Al-4V is recommended for use at temperatures from -350° to 750°F (-210° to 400°C). Applications outside this temperature range are possible in certain situations. The alloy is weldable. Complex shapes can be made via hot forming. It machines like an austenitic stainless steel.
