FASTWELL Titanium Grade 12 is a titanium grade alloyed with molybdenum and nickel. It is characterized by excellent corrosion resistance in reducing and oxidizing environments and offers better heat resistance than pure titanium grades. FASTWELL’s Ti Grade 12 is suitable for applications such as shell and tube heat exchangers and is typically used within chemical industries.
This near-alpha with acicular alpha, alloy combines excellent strength at high temperatures with excellent weldability and crevice corrosion resistance. Beta Transus (F +/- 25) 1634. Equiaxed alpha, primarily in welds or heat-affected zones, small amount of beta. UNS R53400 Titanium Grade 12 is commonly used in applications where there is a high demand of elevated temperature, chemical manufacturing equipment where crevice corrosion is a concern and also marine and airframe components, mildly reducing or variable oxidizing-reducing media - containers, heat exchangers, pumps, valves, pipes and fittings etc.
heat treatment increases corrosion resistance at a lower cost than Pd. Addition of 0.3% Mo and 0.8% Ni to Titanium Gr.12 will increase the strength than unalloyed Ti other grades, yet it remains formable. Tooling should be tungsten carbide C1-C4 or cobalt type high speed tools.
