Titanium manufacturers take you to understand what are GR1 and GR2?

American Standard Gr1

Gr1 was the first of the commercially pure titanium grades. It is the softest and most malleable of these grades. It has maximum formability, excellent corrosion resistance and high impact toughness. Grade GR1 is the material of choice for any application requiring ease of formability and is commonly available as titanium sheet and titanium tubing.

American Standard Gr2

Due to its diverse availability, GR2 grade titanium is known as the "workhorse" of the commercially pure titanium industry. It has many of the same qualities as GR1 grade titanium, but is slightly stronger. Both are equally resistant to corrosion. This grade has good weldability, strength, ductility and formability. This makes GR2 grade titanium rod and plate the first choice for many applications in the construction, power generation, medical industries and many more.
