Titanium Tubes • Grade 12 • UNS R53400

Short Description:

Ti Grade 12 ( UNS R53400 ) 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. Grade 12 shows significant improvement over unalloyed titanium, particularly crevice corrosion in hot brines. It also offers excellent corrosion resistance to acids over unalloyed grades. The higher strength than Grade 2 or Grade 7 at room and elevated temperatures allow material and cost saving through use of thinner sections. Grade 12 is approved by ASME Boiler Code for use up to 600°F. Ti Grade 12 is suitable for applications such as shell and tube heat exchangers and is typically used within, for example, the chemical industries.
