B348 Grade 5 is the American Society for Testing and Materials (ASTM) specification for titanium grade 5 material. Machined components and special fasteners manufactured from B348 Grade 5 have high tensile strength are low in weight and offer reasonable corrosion restance in some environments making them ideal for aerospace use particularly for structural fasteners. B348 Grade 5 can be age hardened to improve the mechanical properties further which can be utilised for turbines and engine components.
