ASTM B265 specifies titanium alloys under the designations Ti 1/2/5/7, each with specific chemical compositions and mechanical properties. Here are the details for each grade:
Ti 1:
Chemical Composition: Pure titanium, consisting mainly of titanium (Ti).
Mechanical Properties: Typically characterized by tensile strength, yield strength, and elongation.
Specific Parameters: Exact chemical composition and mechanical properties depend on the manufacturer and specific requirements but generally high purity and good formability characterize this grade.
Ti 2:
Chemical Composition: Pure titanium with minor impurities.
Mechanical Properties: Similar to Ti 1, including tensile strength, yield strength, and elongation.
Specific Parameters: Chemical composition and mechanical properties may vary slightly depending on the manufacturer and application, but it maintains high purity and good weldability.
Ti 5:
Chemical Composition: Titanium alloy, typically Ti-6Al-4V, consisting of titanium (Ti), aluminum (Al), and vanadium (V).
Mechanical Properties: Exhibits excellent mechanical properties including high strength and corrosion resistance.
Specific Parameters: Chemical composition conforms to ASTM B265 standards, with tensile strength typically around 900 MPa, yield strength over 800 MPa, and elongation around 10%.
Ti 7:
Chemical Composition: Titanium alloy, typically Ti-0.15Pd, consisting of titanium (Ti) and palladium (Pd).
Mechanical Properties: Known for high corrosion resistance and adequate mechanical properties.
Specific Parameters: Chemical composition conforms to ASTM B265 standards, with tensile strength typically around 345 MPa, yield strength over 275 MPa, and elongation around 20%.
These parameters ensure compliance with ASTM standards and are crucial for selecting the appropriate grade for specific applications in various industries, including aerospace, medical, and chemical processing.
ASTM B265 - 20a Titanium and Titanium Alloy Strip, Sheet, and Plate
ASTM B265 covers annealed titanium and titanium alloy strip, sheet, and plate. ASTM B265 Ti and Ti-based alloy plates are widely used in the equipment for the high-temperature environments, including aircraft equipment, petroleum and petrochemical, biomaterial, ocean and chemical industry, for example, blade, storage tank, target, tube and heat-exchanger equipment.
