What Is A Grade 12 Titanium ?

Titanium Grade 12 is a titanium alloy alloyed with Ni, Pd, and Mo with excellent corrosion resistance and higher strength than Titanium Grade 2. Titanium Gr.12 offers excellent corrosion resistance to acids as well as very good resistance to crevice corrosion in hot brines. Due to its higher strength, Titanium Gr.12 can be used with a thinner wall thickness than Titanium Gr.2 or Titanium Gr.7 under the same conditions. Gnee can supply Grade 12 titanium Sheets and Plates/Bars and Rods/Tubes and Pipes/Wires/Forgings/Fittings, etc.

Principal Design Features		This near-alpha alloy combines excellent strength at high temperatures with excellent weldability and crevice corrosion resistance. Beta Transus (F +/- 25) 1634.

Applications		Generally employed in elevated temperature chemical manufacturing equipment where crevice corrosion is a concern. Also applied to a variety of marine and airframe components.

Machinability		As a family, titanium and its alloys have developed a mystique as a nightmare to machine. This is simply not the case. Experienced operators have compared its characteristics to those found in 316 stainless steel. Recommended practice includes high coolant flow(to offset the material's low thermal conductivity), slow speeds and relatively high feed rates. Tooling should be tungsten carbide designations C1-C4 or cobalt type high speed tools.

Forming		May be hot or cold formed using hydropress, power brake, stretch or drop hammer methods. Similar in characteristics to 300 series stainless steels.

Welding		Rated as "excellent" in terms of weldability.

Heat Treatment		Not hardenable by heat treatment.

Forging		Rough work at 871 C (1600 F), finish at 788-843 C (1450-1550 F)

Hot Working		Hot forming will reduce both the springback and required forming forces, and will increase the overall ductility of the material.

Cold Working		The cold work characteristics of this material is similar to that of a moderately tempered austenitic stainless steel. In multiple cold forming operations, intermediate stress relief is recommended to prevent tearing or other material damage. Post-work annealing is required to reattain optimum performance characteristics.

Annealing		Heat to 732-816 C (1350- 1500 F),hold for 2 hours follow by air cooling. For intermediate stress relieving, heat to 538-649 C(1000-1200 F) and hold for 1 hour followed by air cooling.
