Ti-17 Titanium Alloy Description
Ti-17 Titanium Alloy, also known as Ti-5Al-2Sn-2Zr-4Cr-4Mo alloy (UNS R58650), is used as a high strength deep hardening alloy for compressor discs and other large components. Ti-17 Titanium Alloy is a ‘β-rich’ α-β type titanium alloy. This alloy has high strength, good fracture toughness, high hardenability, and wide forging temperature. Its maximum operating temperature reaches 427 ° C. Ti-17 Titanium Alloy can be processed in the beta region or the alpha + beta region. The Ti-17 alloy has a higher tensile and creeps strength than Ti-6Al-4V.
