At <\/span>Daxun Alloy Co. Ltd.<\/span><\/strong>, we supply high-integrity titanium globally, and this guide cuts through the complexity. Whether you\u2019re designing surgical implants or chemical processing equipment, understanding these grades prevents costly mistakes. Let\u2019s dive deep.<\/span><\/p>\n

What is Grade 1 Titanium? The Softest & Most Ductile CP Grade<\/span><\/strong><\/span><\/h4>\n
Grade 1 Titanium: Properties & Characteristics<\/span><\/strong><\/h6>\n

Grade 1 (UNS R50250) is the <\/span>softest, most formable<\/span><\/strong> commercially pure titanium grade. Its minimal oxygen and iron content deliver unmatched ductility.<\/span><\/p>\n

Key Properties (ASTM B265 Standard):<\/span><\/strong><\/h6>\n
    \n
  • Tensile Strength:<\/span><\/strong> 240 MPa (min)<\/span><\/li>\n
  • Yield Strength:<\/span><\/strong> 170 MPa (min)<\/span><\/li>\n
  • Elongation:<\/span><\/strong> 24% (min) \u2013 <\/span>Highest among CP grades<\/span><\/em><\/li>\n
  • Corrosion Resistance:<\/span><\/strong> Exceptional in oxidizing\/chloride environments (e.g., seawater, nitric acid).<\/span><\/li>\n
  • Weldability\/Formability:<\/span><\/strong> Superior cold-forming capability; ideal for complex shapes.<\/span><\/li>\n<\/ul>\n
    Top Applications:<\/span><\/strong><\/h6>\n
      \n
    • \u00a0Chemical processing linings & heat exchangers<\/span><\/li>\n
    • \u00a0Medical implants (bone screws, dental fixtures)<\/span><\/li>\n
    • \u00a0Desalination plants & marine hardware<\/span><\/li>\n
    • \u00a0Architectural cladding requiring extreme bending<\/span><\/li>\n<\/ul>\n

      What is Grade 2 Titanium? The Balanced Workhorse Grade<\/span><\/strong><\/span><\/h4>\n
      Grade 2 Titanium: Properties & Characteristics<\/span><\/strong><\/h6>\n

      Grade 2 (UNS R50400) is the <\/span>most popular CP titanium grade<\/span><\/strong>, offering a balanced blend of strength, corrosion resistance, and affordability. Slightly higher oxygen content than Grade 1 boosts strength while retaining good workability.<\/span><\/p>\n

      Key Properties (ASTM B348 Standard):<\/span><\/strong><\/h6>\n
        \n
      • Tensile Strength:<\/span><\/strong> 345 MPa (min) \u2013 <\/span>~40% stronger than Grade 1<\/span><\/em><\/li>\n
      • Yield Strength:<\/span><\/strong> 275 MPa (min)<\/span><\/li>\n
      • Elongation:<\/span><\/strong> 20% (min)<\/span><\/li>\n
      • Corrosion Resistance:<\/span><\/strong> Near-identical to Grade 1 in most environments. Resists pitting in seawater.<\/span><\/li>\n
      • Weldability\/Formability:<\/span><\/strong> Excellent weldability; moderate cold-forming capability.<\/span><\/li>\n<\/ul>\n
        Top Applications:<\/span><\/strong><\/h6>\n
          \n
        • Aerospace hydraulic tubing & brackets<\/span><\/li>\n
        • Power plant condenser tubes<\/span><\/li>\n
        • Pharmaceutical reaction vessels<\/span><\/li>\n
        • Offshore oil & gas components<\/span><\/li>\n<\/ul>\n

          When to Choose Grade 1:<\/span><\/strong><\/h6>\n
            \n
          • Your design requires <\/span>extreme bending or deep drawing<\/span><\/strong> (e.g., medical mesh).<\/span><\/li>\n
          • Maximum corrosion resistance in <\/span>hot chloride solutions<\/span><\/strong> is critical.<\/span><\/li>\n
          • Weight isn\u2019t a constraint, but failure risk is unacceptable.<\/span><\/li>\n<\/ul>\n
            When to Choose Grade 2:<\/span><\/strong><\/h6>\n
              \n
            • You need <\/span>higher strength without alloying<\/span><\/strong> (e.g., pressure vessels).<\/span><\/li>\n
            • Budget constraints exist, but corrosion resistance can\u2019t be compromised.<\/span><\/li>\n
            • Parts require <\/span>moderate forming + structural reliability<\/span><\/strong> (e.g., aircraft fittings).<\/span><\/li>\n<\/ul>\n

              Critical Note:<\/span><\/strong> Never substitute Grade 2 for Grade 1 in cryogenic applications. Grade 1\u2019s superior ductility prevents brittle fracture below -50\u00b0C.<\/span><\/span><\/em><\/p>\n

              Debunking Common Myths<\/span><\/strong><\/span><\/h4>\n

              Grade 1 vs Grade 2: 3 Misconceptions Clarified<\/span><\/strong><\/p>\n

                \n
              1. \u201cGrade 2 is always better because it\u2019s stronger.\u201d<\/span><\/strong>
                \nLa r\u00e9alit\u00e9 :<\/span><\/strong> Strength isn\u2019t universal. Grade 1\u2019s ductility prevents cracks in dynamic loads (e.g., seismic zones).<\/span><\/li>\n
              2. \u201cCorrosion resistance differs significantly.\u201d<\/span><\/strong>
                \nLa r\u00e9alit\u00e9 :<\/span><\/strong> Both resist seawater, chlorine, and acids equally. Exceptions exist in reducing acids (e.g., sulfuric), where Grade 2\u2019s iron content <\/span>slightly<\/span><\/em> reduces performance.<\/span><\/li>\n
              3. \u201cGrade 1 is obsolete.\u201d<\/span><\/strong>
                \nLa r\u00e9alit\u00e9 :<\/span><\/strong> Medical device approvals (ISO 5832-2) still mandate Grade 1 for permanent implants due to biocompatibility.<\/span><\/li>\n<\/ol>\n

                Conclusion<\/span><\/strong><\/span><\/h4>\n

                Grade 1 titanium dominates when <\/span>ductility and corrosion resistance<\/span><\/strong> are non-negotiable. Grade 2 titanium shines as the <\/span>cost-effective workhorse<\/span><\/strong> for structural applications needing reliability. Neither is \u201cbetter\u201d\u2014success hinges on aligning material properties with engineering demands.<\/span><\/p>\n
