Inserts made from Titanium have a superior strength to weight ratio over 304 Stainless Steel inserts. They also provide very good corrosion resistance and are non-magnetic. Titanium inserts are slightly lower in tensile strength (150,000 to 220,000 PSI) and hardness (Rc 35-43), but are approximately 45% lighter in weight than 304 Stainless Steel inserts, making them ideal where weight reduction is critical. Titanium is very stable and its low coefficient of thermal expansion makes it an excellent choice for use in aerospace applications, such as satellites that must survive temperature fluctuations from sub-zero to 600° F (maximum temperature for insert applications). Titanium is used in biomedical applications; as it is compatible with the human body it is used extensively for applications that involve biological implants. Titanium inserts are covered by material specifications AMS 4957 and AMS 4958A.
