Titanium Gr7’s palladium addition gives it superior corrosion resistance than Grade 2 titanium, especially in highly acidic and cryogenic environments.
Titanium Gr7 (UNS R52400), often referred to as Ti-0.15Pd, is a commercially pure titanium alloy modified by a small addition of palladium (approximately 0.12% – 0.25%). This small addition significantly boosts its resistance to pitting crevice corrosion and stress corrosion cracking, especially in reducing acids and chloride-rich chemical environments.
This alloy maintains the same excellent weldability and moderate strength as Titanium Grade 2 but surpasses it substantially in terms of chemical resistance, making it ideal for highly corrosive and specialized applications.
Titanium Gr7 is composed of the following elements:
Please note that our composition data follows ASTM material specifications for Alloy UNS R52400.
Titanium Gr7 is also known as:
Ti Grade 7 and Titanium Gr2 share similar physical and mechanical properties. However, Grade 7 offers enhanced corrosion resistance due to its palladium content. This makes Grade 7 the preferred choice in applications involving aggressive chemical exposures or seawater.
Ti-0.15Pd alloy is often used in:
