Grade TA9 (American Standard Gr7) is mechanically and physically identical to grade TA2, except that the interstitial element palladium is added to make it an alloy. Grade 7 has excellent weldability and properties and is the most corrosion-resistant of all titanium alloys. It is the most corrosion-resistant among reducing acids. Grade TA9 is used for chemical processes and production equipment components. TA9 has extremely strong corrosion resistance, especially in reducing acidic environments.

TA9 (Gr7) titaniumpalladium alloy is widely used in the aerospace field:
Aircraft structural parts: such as fuselage, wing spars, and other components, using titanium-palladium alloy can reduce the weight of the aircraft and improve flight efficiency.
Spacecraft Department: Such as rocket shells, thrusters, etc., the use of titanium-palladium alloy can provide good structural strength and corrosion resistance.
Titanium-palladium alloys are widely used in the field of medical devices: bone joints, and artificial joints.
TA9 (Gr7)titanium-palladium alloy is widely used in the chemical industry:
Manufacture chemical reactors and chemical pipeline systems to avoid leakage accidents caused by media erosion.
TA9 (Gr7)titanium-palladium alloy can be used in the manufacture of nuclear power plant equipment; titanium-palladium alloy can be used in components in solar panels and solar water heaters.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
