TB-340

TB-340 (Grade 2)

  • Round Bars
  • Hex bars

Characteristics

It is the most common type of titanium grade and is considered to have a good balance of corrosion resistance, strength, weldability, and workability, making it a highly versatile material. Strength is higher than grade 1, but lower than grade 5. Tensile strength is equivalent to low carbon steel.
