ASME SB 265 is the standard specification for titanium and titanium alloy strip, sheet, and plate. GR2, also known as Grade 2 titanium, is one of the titanium alloys covered by this standard. The requirements of GR2 titanium alloy in ASME SB 265 are as follows:
Chemical Composition: GR2 titanium alloy must conform to specific chemical composition requirements. The composition typically includes a minimum of 99.2% titanium, with small amounts of other elements such as oxygen, iron, carbon, nitrogen, and hydrogen.
Mechanical Properties: The standard specifies the mechanical properties that GR2 titanium alloy must meet. These properties include minimum tensile strength, yield strength, and elongation. For example, the minimum tensile strength of GR2 titanium is 345 MPa (50 ksi), the minimum yield strength is 275 MPa (40 ksi), and the minimum elongation is 20%.
Dimensions and Tolerances: ASME SB 265 provides specifications for the dimensions and tolerances of GR2 titanium strip, sheet, and plate. This includes requirements for thickness, width, length, flatness, straightness, and surface finish.
Testing and Certification: The standard outlines the testing methods and requirements for GR2 titanium alloy. This includes tests such as chemical analysis, tensile testing, hardness testing, and visual inspection. The material must also be accompanied by appropriate certifications and documentation to verify compliance with the standard.
It's important to note that the specific requirements of GR2 titanium alloy in ASME SB 265 may vary depending on the thickness, size, and other factors. Therefore, it is recommended to refer to the latest version of the standard for detailed and up-to-date information on the requirements of GR2 titanium alloy in ASME SB 265.
