The production process of medical titanium rod is:
Relief anneal at 900-1200°F for 1-4 hours, air cool. Double annealed, round bars and forgings are solution annealed at 50-100°F beta transition temperature, held at least 1 hour in air, then reheated at 1300-1400°F, held at least 1 hour in air. Relaxation annealing is suitable to be carried out after welding.
Medical Titanium Rod Technological process: Select grade 0 sponge titanium, cast titanium ingots for 3 times, and forge billets through high-temperature piers for many times, hot-rolled to the required billet size, machined, drawn, heat-treated, straightened, polished, and non-destructive. Flaw detection, finishing and polishing to finished bar
Physical properties: The tensile strength of the TC4 medical bar is 980-1050Mpa, the yield value is 960-1000Mpa, the elongation after fracture is 25%, and the area shrinkage rate is 45%. High power structure A1-A2
Medical Titanium Rod Quality supervision: starting from the sponge titanium for composition testing, after the ingot is formed, the upper, middle and lower samples are taken for composition testing, and ultrasonic non-destructive testing is carried out to ensure the quality of the ingot material, and the riser and bottom of the ingot are cut off. , After processing to the finished product, the physical properties are tested by batch sampling to ensure that the product performance is up to standard.
Medical Titanium Rod Product advantages: TC4 medical titanium alloy bar has high strength, good biocompatibility, and the high tolerance level of shape and position tolerance is generally (h8, h9). Mainly used in joints, spine and other human orthopedic implants and surgical instruments.
Medical Titanium Rod Specifications: rolling ￠8.0---40mm×L; forging ￠40---150mm×L
Metallographic structure: The grain size of pure titanium is not less than grade 5, and the TC4 titanium alloy conforms to A1-A9.
Surface: black leather surface, car polished surface, polished surface (H11, H9, H8)
