Titanium Grade 12, Annealed
Categories: Metal; Nonferrous Metal; Titanium Alloy; Unalloyed/Modified Titanium

Material Notes: Addition of 0.3% Mo and 0.8% Ni to titanium increases corrosion resistance at a lower cost than Pd (see Ti Grades 7 and 11). Sample was annealed 20 min. at 815°C and 5 min. at 788°C.

Higher strength than unalloyed Ti grades 1 - 4, yet still formable.

Microstructure: Equiaxed alpha, with acicular alpha, primarily in welds or heat-affected zones, small amounts of beta.

Applications: Chemical processing, in mildly reducing or variable oxidizing-reducing media - containers, heat exchangers, pumps, valves, pipes and fittings.

Forms typically available: billet, bar, rod, plate, sheet, strip and tubing.

Titanium Grades 1,2,3,4,7,11,and 12 are all considered unalloyed and have similar mechanical properties.

Key Words: UNS R53400; ASTM Grade 12, titanium alloy
Vendors: Visit metalmen for your metals needs. Products include special chemistry, tight tolerances, custom tempers, odd dimensions/forms, and small quantities. Phone 1-800-767-9494.
