Titanium Seamless Tubing Grade 2
GR2 is a common titanium alloy material in industry. It is usually formulated and produced according to the standards of ASTM (American Society for Testing and Materials).
Description
As a common industrial pure titanium, Grade 2 titanium has excellent corrosion resistance. In seawater, salt water, wet chlorine gas, and some dilute acid and dilute alkali solutions, Grade 2 titanium shows strong corrosion resistance, which is far superior to ordinary stainless steel and carbon steel.
