SAE AMS 4917H
This specification covers a titanium alloy in the form of sheet, strip, and plate through 4.00 inches (101.6 mm)..This material has been used typically for parts to be formed in the solution heat treated condition and subsequently precipitation heat treated, requiring high strength-to-weight ratio and stability up to 550 mDF (288 mDC) in the precipitation heat treated conditions, but usage is not limited to such applications.This alloy may have poor crack propagation resistance in the precipitation heat treated condition.Certain processing procedures and service conditions may cause these products to become subject to stress-corrosion cracking; ARP982 recommends practices to minimize such conditions.
