Titanium Grade 12

Aurico Alloys LLP supplies Titanium Grade 12 (UNS R53400) as sheet, plate, foil and round bar, from Mumbai, India, with EN 10204 3.1 mill test certificates. Alloyed with molybdenum and nickel for superior strength at 300°C, it is used in chemical processing, oil & gas, marine desalination, pharma vessels and power heat exchangers.

Key Properties

Nickel 0.6-0.9% with molybdenum 0.2-0.4% — a lean alloy addition that buys crevice corrosion resistance without palladium's cost.
Better than Grade 2 in hot brines and chlorides, though not the equal of Grade 7.
Weldable and formable much like the commercially pure grades.
Oxygen 0.25% and iron 0.30% maximum.

Applications

Hot brine and chloride process equipment
Heat exchangers and condensers
Geothermal and hydrometallurgical plant

TIMET places Grade 12 between unalloyed titanium and Grade 7 in reducing acids: about 9% hydrochloric acid at room temperature, against 7% and 27%, and about 1% sulphuric acid at boiling. See how it compares in our acid and alkali service guide.
