Titanium Grade 7 Round Bar (UNS R52400)
Titanium Grade 7 Round Bar is a palladium-enhanced commercially pure titanium alloy that delivers exceptional corrosion resistance, especially in reducing acids and chloride-rich environments. It combines the formability and weldability of Grade 2 titanium with superior resistance to crevice and pitting corrosion, making it ideal for demanding chemical and marine applications.
Key Features
- Outstanding corrosion resistance in reducing and oxidizing acids
- Excellent resistance to crevice and pitting corrosion
- Superior performance in chloride and seawater environments
- Good weldability and fabrication properties
- Lightweight, non-magnetic, and biocompatible
- Long service life in aggressive chemical conditions
