ASTM B348 Grade 5 titanium rod (titanium bar) is an alpha-beta titanium alloy bar produced and tested to ASTM B348\/B348M. It is Ti-6Al-4V, UNS R56400. Aluminum is the alpha stabilizer and vanadium is the beta stabilizer, giving the alloy high specific strength, corrosion resistance and the capability for heat-treatment strengthening.<\/p>

Grade 5 is one of the most widely used engineering titanium alloys. When the strength of commercially pure Grades 1-4 is insufficient, Grade 5 provides substantially higher load-carrying capability. Its strength, fatigue potential, heat-treatability and corrosion resistance suit parts with demanding mass and structural-reliability requirements; its cold-forming latitude and post-weld property control are correspondingly more demanding than for CP titanium.<\/p>

Grade 5 rod\/bar is used for aerospace structural parts, high-strength fasteners, shafts, connectors, valves, pump components, motorsport and sporting-goods parts, marine hardware and high-performance machined parts. It may also be used as raw material for medical devices and implants only when the applicable specification is satisfied.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Application boundary:<\/strong> ASTM B348 is an industrial titanium-alloy bar and billet specification. Surgical implant use cannot be justified by an ASTM B348 Grade 5 certificate alone and may require ASTM F136 or another applicable medical specification, the customer drawing, regulations and a suitable quality system.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Main Characteristics<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
  • High strength and high specific strength:<\/strong> Annealed ASTM B348 material has a minimum tensile strength of 895 MPa, minimum 0.2% offset yield strength of 828 MPa and minimum elongation of 10%, supporting high-strength, weight-efficient structural parts.<\/li>
  • Heat-treatable alpha-beta alloy:<\/strong> Solution treatment and aging can provide higher strength. Actual properties depend on section size, heat-treatment schedule and the qualified manufacturing process.<\/li>
  • Excellent strength-to-weight potential:<\/strong> Density is approximately 4.43 g\/cm\u00b3, about 56% of steel density, while delivering high strength for aerospace and performance engineering applications.<\/li>
  • Good fabricability with controlled machining:<\/strong> Grade 5 can be forged, rolled, drawn, turned, milled, drilled, ground and threaded. Its low thermal conductivity and tendency to gall require titanium-appropriate tools, cutting parameters and coolant.<\/li>
  • Good corrosion resistance:<\/strong> A stable titanium-oxide passive film forms naturally and provides useful resistance in many seawater, oxidizing and general industrial environments.<\/li>
  • Weldability with safeguards:<\/strong> TIG, MIG, plasma, laser and electron-beam welding may be used with complete inert-gas shielding. Critical load-bearing welds require qualified procedures and assessment of weld properties and any post-weld heat treatment.<\/li>
  • Essentially non-magnetic:<\/strong> Useful in some equipment and instruments sensitive to magnetic response.<\/li>
  • Service temperature and microstructure must be controlled:<\/strong> Long-term temperature, heat-treatment condition, microstructure and surface condition must be confirmed against the applicable design specification rather than general product literature alone.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Technical references:<\/strong> ASTM B348\/B348M, ATI Ti-6Al-4V Grade 5 data and related Grade 5 product data.<\/li>
    • Aluminum and vanadium:<\/strong> Aluminum stabilizes alpha and vanadium stabilizes beta. Their controlled combination gives Grade 5 its alpha-beta microstructure and heat-treatability.<\/li>
    • Oxygen, nitrogen, carbon and hydrogen:<\/strong> These must be controlled. Oxygen, nitrogen and carbon can increase strength but reduce ductility and toughness; excessive hydrogen may form brittle hydrides and increase embrittlement risk.<\/li>
    • Titanium content:<\/strong> ASTM states Titanium: Balance. Final chemistry shall be confirmed by the original mill test report for the applicable heat.<\/li>
    • Lot acceptance:<\/strong> If an order cites an AMS, medical specification or customer drawing, its composition limits and additional element requirements may be stricter than ASTM B348 and must be confirmed separately.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
