Key Specifications
ASTM B265 titanium plate refers to flat-rolled titanium and titanium alloy products manufactured in accordance with ASTM B265, the standard specification issued by ASTM International for titanium plate, sheet, and strip.
Material
The standard applies to titanium (Grade 1 to Grade 4) and titanium alloys (Grade 5, Grade 7, Grade 9, Grade 12, Grade 23, and others) in the form of plates, sheets, and strips.
It covers titanium grades with various properties suitable for different applications, including aerospace, medical devices, and chemical processing.
Thickness
The plates and sheets can vary in thickness, typically ranging from 0.020 inches (0.5 mm) to 4 inches (102 mm) or more, depending on the specific grade and application.
Width
Widths of the plates or sheets generally range from 12 inches (305 mm) to 72 inches (1830 mm), or custom widths as specified by the customer.
Length
Lengths of the plates and sheets usually range from 36 inches (914 mm) to 144 inches (3658 mm), or can be cut to custom lengths
Mechanical Properties
- Tensile Strength: Varies depending on the grade, for example:
① Grade 1 (unalloyed) has a minimum tensile strength of 35,000 psi (241 MPa).
② Grade 5 (Ti-6Al-4V alloy) has a minimum tensile strength of 130,000 psi (896 MPa).
- Yield Strength: Also grade-dependent, for example, Grade 5 has a minimum yield strength of 120,000 psi (827 MPa).
Surface Finish
Titanium plates and sheets per ASTM B265 may have various surface finishes such as mill finish, polished, or etched surfaces.
Chemical Composition
The titanium grades under ASTM B265 are defined by specific chemical composition limits, including the percentage of titanium, aluminum, vanadium, iron, oxygen, and other elements, depending on the alloy grade.
Fabrication & Tolerances
Plates and sheets manufactured under ASTM B265 should meet the specified tolerances for dimensions, flatness, and surface quality.
Applications
Aerospace Chemical processing, Marine, Medical applications .
This standard ensures uniformity in the properties and dimensions of titanium plates, enabling their reliable use in demanding applications.
