Titanium Forged Ring has plasticity, high purity titanium elongation up to 50-60%, section shrinkage up to 70-80%, but low strength, not suitable for structural materials. The presence of impurities in titanium has a great impact on its mechanical properties, especially interstitial impurities (oxygen, nitrogen, carbon) can greatly increase the strength of titanium and significantly reduce its plasticity. Titanium as a structural material with good mechanical properties is achieved by strictly controlling the appropriate content of impurities in it and adding alloying elements.
Production process:
Forging, die forging, rotary forging, precision forging, welding Testing Tensile strength test, hardness test, chemical composition test, ultrasonic test, ray test, penetration coloring test. Surface Surface treatment: turning and chamfering. Surface quality: the surface roughness Ra value of the two end surfaces should be no more than 3.2lμm (subject to ultrasonic inspection requirements), the surface roughness Ra of the inner and outer surfaces should be no more than 12.5μm (Ra should be no more than 3.2μm when ultrasonic inspection is required for the outer circumferential surfaces), and the chamfering radius should be 5~15mm. Application areas Aerospace, aviation, military, light industry, chemical industry, textile, medical and petrochemical fields.
Applications:
The surface roughness Ra of the inner and outer surfaces should be no more than 12.5μm (Ra should be no more than 3.2μm when ultrasonic flaw detection is required for the outer circumference), and the chamfering radius should be 5-15mm. Application Areas Aerospace, aviation, military, light industry, chemical industry, textile, medical and petrochemical industries, and so on.
Titanium Forging is a specialized set of manufacturing processes used to create parts from titanium alloys. Due to the advantages of titanium and titanium alloys, such as low density, high specific strength and good corrosion resistance, the Titanium Forging Process is widely used in a variety of fields.... Titanium Alloy forging, due to the expensive material, more suitable for forging molding, not only to improve the internal quality of components, but also to save metal materials. Each link of forging has more or less influence on the internal quality or appearance of forgings. Therefore, must be strictly in accordance with the forging process to complete each process. The blanks for forging cake rings must be circular sawn, and must be chamfered after sawing. Strictly implement the process card upsetting deformation, upsetting, must remember the original axial and radial to ensure that the final return to the original axial to ensure the correctness of the flow. Observe diligently when upsetting, and correct the distortion in time to prevent folding. The cake material is based on the requirements of the process card after upsetting, and finally after heating and shaping to become the required size of the cake material, and its tolerance according to the requirements of the process card.
Titanium forgings standard: GBT16598 ASTM B381
Delivery state: annealed state (M) hot working state (R) cold working state (Y) (annealed, ultrasonic flaw detection) surface treatment: turning, chamfering surface quality: the two end surfaces of the surface roughness Ra should be no more than 3.2lum (to meet the ultrasonic inspection requirements prevail), the inner and outer side of the surface roughness Ra should not be more than 12.5um (Ra should be no more than 3.2um when ultrasonic inspection is required for the outer circumference), chamfer radius is 5~15mm, the product surface should not have cracks, folding, heavy skin and other defects visible to the naked eye. The surface of the local defects are allowed to remove the method of grinding, cleaning depth should not exceed its size tolerance, and should ensure that the minimum allowable size.
The ratio of cleaning depth to width should be no more than 1: 6 on both ends, and no more than 1: 10 on the inner and outer sides, and the outer sides should be ground axially. Surface finish: clean, dust-free, better acid resistance life. Test: Mechanical properties, chemical composition test, ultrasonic detection.
