ASTM B348 Standard Requirements For Titanium Bar
1. Chemical composition: Titanium bars should have a minimum purity of 97.5% titanium with allowances for certain elements, such as aluminum, vanadium, iron, and oxygen.
2. Mechanical properties: Titanium bars must meet minimum requirements for tensile strength, yield strength, and elongation.
3. Dimensions and tolerances: Titanium bars must meet specific requirements for diameter, length, and straightness, as well as tolerances for these dimensions.
4. Surface finish: Bars must have a smooth and clean surface without any cracks, seams, or other surface defects.
5. Heat treatment: Bars must undergo a specific heat treatment process, such as annealing, to ensure proper microstructure and uniformity.
6. Sampling, testing, and inspection: Bars must be subjected to testing and inspection procedures to ensure they meet all relevant requirements.
7. Workmanship and finish: Bars must exhibit good workmanship and finishing, with no signs of burrs, sharp edges, or roughness.
8. Packaging and marking: Bars must be properly packaged and marked for identification and tracking purposes.
