Ti 3Al-8V-6Cr-4Mo-4Zr

UNS #R58640

Ti-3Al-8V-6Cr-4Mo-4Zr is a metastable beta alloy that is heat-treatable to a wide range of strength levels and used when particularly high strengths are needed along with light weight and corrosion resistance. Offers low elastic modules and excellent fatigue resistance. Also known as Ti-3-8-6-4-4, Beta-C TM or ASTM B348 Grade 19, it is one of the easier beta alloys to melt, exhibiting low segregation, and to process, exhibiting good working and heat treating properties.
