| 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. | Comprehensive range of plate, bar, pipe and tube 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 - 0.20O |
| 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 |
Heat and/or creep resistant
