Scope

Main Technical Content: Requirements: 1. Materials 1.1 The casting ingots used for product production shall undergo multiple melting processes. The first melting can be conducted using a vacuum self-consuming arc furnace or a cooling bed furnace, and subsequent melting shall always use a vacuum self-consuming arc furnace, with no addition of any elements allowed during the final melting. 1.2 It is prohibited to use recycled materials from other titanium alloys as raw materials for casting ingots and machining materials. 1.3 Tungsten electrodes are not allowed for welding during self-consuming electrode welding. 2. Chemical Composition 2.1 The chemical composition of the product shall comply with the requirements in Table 1. 2.2 When the buyer conducts reinspection, the allowable deviations in the chemical composition of the product shall comply with the provisions of GB/T 3620.2. 3. Heat Treatment 3.1 The recommended heat treatment regime for solution annealing is: 600°C–650°C, holding time 0.5–1 h, and water cooling. 3.2 The supplier may adjust the heat treatment regime as needed. 4. Product Classification 4.1 The composition, state, and specifications of the material shall comply with the requirements in Table 2. Note: The recommended annealing regime is 600°C–650°C with a holding time of 1 h. 4.2 Shape and Dimensions 4.2.1 The shape and allowable deviations of rod materials shall comply with the relevant provisions of GB/T 2965. 4.2.2 The shape and allowable deviations of wire materials shall comply with the relevant provisions of GB/T 3623. 4.2.3 The shape and allowable deviations of plate materials shall comply with the relevant provisions of GB/T 3621. 4.3 Tensile Properties The room-temperature tensile properties shall comply with the requirements in Table 3. Table 3: Room-temperature tensile properties. 4.4 Bending Properties Boards with a diameter not exceeding 5 mm shall undergo bending tests, and the bending di
