Definition of Grade 2 ASTM B337 Titanium tubing
Grade 2 ASTM B337 Titanium tubing are tubular materials made from industrially pure titanium (such as Grade 1, Grade 2, and Grade 3). Their high purity and low impurity content result in both high strength and excellent corrosion resistance. These tubes are lightweight, high-strength, and corrosion-resistant, making them widely used in chemical, aerospace, marine engineering, medical equipment (such as dental implants), and heat exchangers.
Typical grades of pure titanium tubes include Grade 1, Grade 2, and Grade 3. Gr1, with a purity of up to 99.99%, exhibits good corrosion resistance in many media, while also possessing excellent weldability and machinability.
For example, it is used in the chemical industry to manufacture heat exchangers and condensers, and in the medical field, it is frequently used in implants such as dental implants due to its good biocompatibility.
Furthermore, pure titanium tubes have advantages such as low density, high heat transfer efficiency, and require no maintenance, making them suitable for long-term use in high-temperature and corrosive environments.
Specification of Grade 2 ASTM B337 Titanium tubing
Common specifications for ASTM B337 pure titanium tubing are as follows:
