Titanium Based Alloys

Titanium Based Alloys
Titanium and its alloys are useful engineering materials because of their excellent resistance to corrosion in oxidizing environments and / or high strength to weight ratio. They also offer resistance to erosion by flowing solutions with entrained solids and good heat transfer characteristics.

GRADE		MAJOR APPLICATIONS	AVAILABILITY	COMPOSITION
	TI GRADE 12 UNS R53400	Grade 12 is a highly weldable and fabricable alloy offering improved strength and pressure vessel code allowances compared to Grade 2. It also has corrosion resistance advantages.	Imported; ex-stock or mill availability.	98.5Ti - 0.3Mo - 0.8Ni (controlled interstitials)
	TI GRADE 16 UNS R52402	A lower cost, leaner Pd version of Grade 7 with equivalent mechanical and physical properties and corrosion resistance between that of Grades 7 and 2.	Imported; ex-stock (limited) or mill availability.	99.5Ti - 0.05Pd (controlled interstitials)
	TI GRADE 2 UNS R50400	Moderate strength unalloyed grade of titanium with excellent weldability, cold formability and fabricability; "workhorse" grade for industrial service. It displays excellent resistance to a wide range of conditions ranging from mildly reducing to highly oxidising.	Selected items from stock; or imports from stock or mill availability.	99.5Ti - 0.03N - 0.30Fe - 0.25 O
	TI GRADE 4 UNS R50700	Much stronger version of Grade 2 as a result of the higher level of interstitial elements. It has reasonable weldability but reduced ductility and formability. Widely used for plating and anodising jigs and fixtures.	Imported; ex-stock (limited) or mill availability.	99.3Ti - 0.05N - 0.50Fe - 0.40 O
	TI GRADE 5 UNS R56400	Heat treatable, high strength, most commercially available titanium grade for use up to 400 deg c.- "workhorse" grade for the aerospace industry. Offers excellent combination of strength, toughness and ductility along with good weldability and fabricability. Grade 23 is a variant having extra low interstitial elements and thus improved ductility and fracture toughness.	Imported; ex-stock or mill availability.	89.3Ti - 6Al - 4V - 0.05N - 0.40Fe - 0.20
	TI GRADE 7 UNS R52400	The titanium alloy most resistant to corrosion in reducing acids and to localised attack in hot halide media. It has physical and mechanical properties equivalent to Grade 2 and excellent weldability / fabricability.	Imported; ex-stock or mill availability.	99.3Ti - 0.2Pd - 0.03N - 0.30Fe - 0.25O
