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

ASTM B265 Grade 4 titanium sheet and plate are commercially pure titanium flat products produced and tested to ASTM B265. The alloy is UNS R50700. Grade 4 is the highest-strength of the four common commercially pure titanium grades, combining good corrosion resistance and weldability with moderate ductility for chemical processing, marine, energy and heat-transfer equipment.<\/p>

Grade 4 is principally titanium with controlled oxygen, iron, nitrogen, carbon and hydrogen. Compared with Grade 3, Grade 4 permits higher oxygen and iron, providing the highest strength of the four common CP titanium grades with correspondingly lower ductility and cold-forming response. It is commonly supplied annealed and is suitable for cutting, bending, welding, machining and qualified forming processes. Formal acceptance shall follow the ASTM B265 edition, thickness, condition, test direction and supplementary requirements stated in the order.<\/p>

Grade 4 sheet and plate are suitable for chemical vessels and linings, reactors, tower internals, heat exchangers, condensers, desalination and marine hardware, hydrometallurgical equipment, oil-and-gas and energy systems, clad-plate backing and other corrosion-resistant sheet-metal or equipment components where higher CP titanium strength is beneficial.<\/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
  • Highest strength with moderate formability:<\/strong> Grade 4 is stronger than Grade 3 while retaining good corrosion resistance and weldability. Its cold-forming response is lower than Grade 1, Grade 2 and Grade 3. It can be used for bending, stamping, deep drawing, spinning and explosive bonding; complex forming should be qualified by trial or an approved process.<\/li>
  • ASTM B265 mechanical requirements:<\/strong> Grade 4 sheet and plate have a minimum tensile strength of 550 MPa, a minimum 0.2% offset yield strength of 483 MPa and a minimum elongation of 15%. Formal acceptance must consider ordered thickness, supply condition and the applicable ASTM B265 requirements.<\/li>
  • Excellent corrosion resistance:<\/strong> A continuous, tightly adherent titanium-oxide passive film gives Grade 4 excellent performance in many oxidizing media, seawater, brines and chloride-bearing aqueous environments. Actual selection must consider medium, temperature, concentration, flow, oxygen availability and crevice conditions.<\/li>
  • Good weldability:<\/strong> TIG, MIG, plasma, laser and electron-beam welding may be used. The weld area must be clean and the weld pool, face, root and hot heat-affected zone require complete high-purity inert-gas shielding.<\/li>
  • Low density and essentially non-magnetic behavior:<\/strong> Density is about 4.51 g\/cm\u00b3, supporting corrosion-resistant lightweight equipment and some magnetic-response-sensitive uses.<\/li>
  • Not significantly strengthened by conventional heat treatment:<\/strong> Annealing and stress-relief annealing for CP Grade 4 principally stabilize microstructure, improve fabrication response and relieve residual stress. Special thermal condition, flatness, surface, ultrasonic examination or corrosion-testing requirements 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

    • Oxygen:<\/strong> Grade 4 has a maximum oxygen content of 0.40%. Oxygen increases strength but reduces ductility and formability; oxygen content and product processing condition affect final properties.<\/li>
    • Nitrogen, carbon, hydrogen and iron require close control. Excess nitrogen and carbon reduce ductility; excessive hydrogen can form brittle hydrides; iron affects strength, microstructure and corrosion behavior.<\/li>
    • Final chemistry shall be confirmed by the original mill test report for the applicable heat. More-stringent customer drawings, ASME, NACE, ASTM B265 or other applicable requirements must be stated during quotation and ordering.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
