Principal Design Features This is the most commonly used and widely available grade of unalloyed titanium. The grade combines excellent corrosion resistance and weldability with good strength, ductility and formability. Beta Transus (F +/- 25) 1675. Types Titanium Gr.2 With moderate strength and excellent corrosion resistance and formability, Grade 2 titanium represents the most widely used form of titanium. Compared to the other grades of commercially pure titanium, Grade 2 titanium is slightly weaker than Grade 3, but stronger than Grade 1 and equally resistant to corrosion. These properties account for Grade 2 titanium's versatility in regard to its applications.
