ASTM B338 Annealed Centreless Ground Grade 2 Titanium Rods
Ground Grade 2 Titanium Rods have poor stamping property and good thermoplasticity. Gr2 titanium rod can be welded in various forms, and the strength of the welded joint can reach 90% of the strength of the base metal. The mechanical processing performance is good, and cemented carbide tools are required, with large cutting amount, slow speed and sufficient cooling. Good corrosion resistance and thermal stability.

Application of Gr2 Titanium rods
Titanium bars have been widely used in aerospace, chemical, nuclear industry, sports equipment and other fields because of their high temperature resistance, high corrosion resistance, high strength, low density and biocompatibility. It is also one of the main structural materials of contemporary aircraft and engines.
