Product Overview<\/h2>\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

HTN coordinates the supply of ASTM B348 Grade 1 titanium bar through evaluated manufacturing partners. The applicable standard edition, grade, dimensions, condition, inspection documents and any additional testing requirements are confirmed for each order. Order-specific MTCs and heat or lot traceability documents are available as agreed.<\/p>

Grade 1 titanium bar combines low density, excellent corrosion resistance, good weldability and high ductility. It is well suited to components that require cold forming, resistance to chloride-bearing environments and controlled material purity, provided that very high structural strength is not the primary design requirement.<\/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
  • Excellent ductility and formability: <\/strong>Grade 1 is the most formable of the commonly used CP titanium grades and is suitable for cold bending, spinning, stamping and other substantial plastic deformation.<\/li>
  • Excellent corrosion resistance: <\/strong>A dense and stable titanium-oxide passive film forms naturally on the surface and can repassivate when oxygen or moisture is available.<\/li>
  • Low density: <\/strong>Its density is approximately 4.51 g\/cm\u00b3, about 60% of that of ordinary steels.<\/li>
  • Good weldability: <\/strong>Grade 1 can be welded by TIG\/GTAW, plasma and electron-beam processes, provided that the weld pool, completed weld and hot heat-affected zone are fully shielded.<\/li>
  • Good low-temperature toughness: <\/strong>CP titanium does not normally show the pronounced ductile-to-brittle transition associated with some steels.<\/li>
  • Not significantly strengthened by conventional heat treatment: <\/strong>Strength is controlled mainly through interstitial chemistry, grain size and cold work; annealing restores ductility and relieves processing stress.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Oxygen and nitrogen: <\/strong>Increase strength and hardness, but excessive levels reduce ductility, toughness and formability.<\/li>
    • Iron: <\/strong>Contributes to strength; excessive iron may affect microstructural uniformity and corrosion performance.<\/li>
    • Hydrogen: <\/strong>Must be strictly controlled because excessive hydrogen may form hydrides and increase embrittlement risk.<\/li>
    • Titanium content: <\/strong>ASTM uses \u201cTitanium: Balance.\u201d A fixed statement such as \u201cTi \u226599.5%\u201d should not be used unless supported by the actual heat analysis or an additional producer guarantee.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
