ASTM B348 Grade 9 titanium rod\/bar is a Ti-3Al-2.5V low-alloy alpha-beta titanium bar produced and tested to ASTM B348\/B348M. The alloy is UNS R56320, with 2.5% to 3.5% aluminum and 2.0% to 3.0% vanadium. Its room-temperature microstructure is typically alpha plus beta, predominantly alpha with a limited beta phase fraction.<\/p>

Compared with commercially pure Grade 2 titanium, Grade 9 offers substantially higher strength and specific strength while retaining good cold formability, weldability and corrosion resistance. Compared with Grade 5, it is generally lower in strength but less highly alloyed and well suited to applications requiring forming, low weight and moderate strength. It is commonly supplied annealed; formal acceptance shall follow the contract edition, condition, dimensions and supplementary requirements.<\/p>

Grade 9 bar is suitable for aircraft hydraulic-system components, lightweight structural parts, fasteners, turned and milled parts, bicycles and sporting goods, marine hardware, chemical-process equipment components and other engineered parts requiring corrosion resistance, weldability and higher strength.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\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
  • Moderate strength and excellent strength-to-weight ratio:<\/strong> ASTM B348 minimum tensile strength is 620 MPa, minimum 0.2% offset yield strength is 483 MPa and minimum elongation is 15%, substantially above commercially pure Grade 2.<\/li>
  • Good cold formability:<\/strong> Grade 9 generally offers better cold bending, flaring, reducing and general forming latitude than high-strength Grade 5, supporting parts that need both strength and subsequent forming.<\/li>
  • Good weldability:<\/strong> TIG, MIG, plasma, laser and electron-beam welding may be used with complete high-purity inert-gas shielding of the weld pool, face, root and hot heat-affected zone.<\/li>
  • Machinable and hot-workable:<\/strong> The alloy can be forged, hot rolled, drawn, turned, milled, drilled, ground, bent and stamped. Use rigid equipment, sharp tooling and non-chlorinated cutting fluid; avoid dwell, rubbing and localized overheating.<\/li>
  • Low density and essentially non-magnetic behavior:<\/strong> Density is about 4.48 g\/cm\u00b3, supporting lightweight design and some magnetic-response-sensitive uses.<\/li>
  • Supply condition must be defined:<\/strong> Grade 9 is a low-alloy alpha-beta titanium alloy. Annealed is the common supply condition. Solution treatment, aging, stress relief, microstructure, hardness or special strength ranges must be stated in the order and qualified by an approved process when required.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Aluminum and vanadium are the defining alloying elements. Aluminum stabilizes alpha and vanadium stabilizes beta; their controlled balance governs Grade 9 strength, fabricability and alpha-beta microstructure.<\/li>
    • Oxygen, nitrogen, carbon, hydrogen and iron must be controlled. Oxygen, nitrogen and carbon raise strength but can reduce ductility; excessive hydrogen can form brittle hydrides, while iron segregation can affect microstructural and property uniformity.<\/li>
    • Final chemistry shall be confirmed by the original mill test report for the applicable heat. Any more-stringent drawing, AMS, ASME, ASTM B861\/B338 or customer requirement must be stated in the order.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
