	PRODUCT DATA of Ti 10V 2Fe 3Al

Material

Ti 10V 2Fe 3Al

Product Datasheet

Ti 10-2-3

General Information

Ti-10V-2Fe-3Al is a solute lean beta (near beta) titanium alloy that was developed primarily as a high-strength forging alloy. It has excellent forging characteristics, possessing flow properties at 815C similar to Ti-6Al-4V at 925C. This characteristic provides advantages, such as lower die cost and better die fill capability. This alloy also provides the best combination of strength and toughness of any of the commercially available titanium alloys From mmpds

Welding

Nitrogen, hydrogen, carbon dioxide, and mixtures containing these gases shall not be used Welding with alloy-matching fillers is recommended, preferably using extra Low Interstitial (ELI) filler wires

	SPECIAL RECOMMENDATIONS

Lessons Learned

A great deal of care needs to be exercised to ensure complete inert gas (argon or helium) coverage during welding.
