ASTM F67 Grade 2 unalloyed titanium bar is wrought commercially pure titanium bar used to manufacture surgical implants, UNS R50400. Among the four unalloyed grades in ASTM F67, Grade 2 combines moderate strength with good ductility and fabricability and is one of the most widely used commercially pure titanium grades for medical-device raw material. Its properties are controlled principally through oxygen, iron, nitrogen, carbon and hydrogen limits.<\/p>

The material offers good biocompatibility, resistance to physiological corrosion, weldability and balanced mechanical performance for medical-device raw material requiring higher strength than Grade 1 while retaining good forming and machining capability. ASTM F67 compliance applies to the raw material; it does not mean a finished implant has completed design verification, biological evaluation, cleaning, sterilization or regulatory approval.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Medical-use boundary:<\/strong> ASTM F67-compliant bar is medical-device raw material, not an approved finished implant.

Main Characteristics<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
  • Balanced strength and ductility:<\/strong> Annealed Grade 2 is stronger than Grade 1 while retaining good elongation, cold formability and processing versatility.<\/li>
  • Controlled unalloyed chemistry:<\/strong> No nominal alloying addition is made; O, Fe, N, C and H are controlled to balance strength, ductility, toughness and lot consistency.<\/li>
  • Good biocompatibility:<\/strong> A stable TiO2 passive film helps limit ion release in physiological environments. The finished device still requires applicable biological evaluation.<\/li>
  • Good corrosion resistance:<\/strong> Performance is generally excellent in saline, body fluids and many chlorides, but crevices, fretting corrosion, dissimilar-metal coupling and fluoride exposure require device-level evaluation.<\/li>
  • Good weldability:<\/strong> Qualified inert-gas, laser or resistance welding may be used; hot metal must be protected from O, N, H and C contamination.<\/li>
  • Moderate-strength grade:<\/strong> Grade 2 suits many medical-device parts but is not the highest-strength unalloyed titanium grade. Load-bearing implants require design verification using actual load, fatigue, geometry, surface condition and service-life requirements.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Oxygen and iron:<\/strong> Oxygen is an important interstitial strengthener in unalloyed titanium, and iron also increases strength. Grade 2 permits higher oxygen and iron limits than Grade 1, providing higher strength with somewhat lower formability.<\/li>
    • Nitrogen, carbon and hydrogen:<\/strong> These elements require strict control. Excess content raises hardness and reduces ductility; hydrogen may promote hydrides and embrittlement.<\/li>
    • Residual elements:<\/strong> Each and total limits must be controlled. Testing only the principal impurities does not satisfy the full chemistry requirement.<\/li>
    • Titanium content:<\/strong> The specification states Titanium: Balance. A nominal purity claim does not replace heat-specific chemical analysis and the material report.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
