• Pipe: outer diameter 3-500mm, wall thickness 0.2-30mm (seamless pipe pressure resistance is better).
• Surface preparation :
• Annealing pickling (stress removal), sandblasting (enhanced wear resistance), mirror polishing (BA / 8K grade).
•Criterion of detection :
• Chemical composition (titanium content of 99.6%, strict impurity control) 13.
• Mechanical properties test (tensile, shock, hardness) and non-destructive testing (ultrasonic, penetration detection).
Technical parameters
• Mechanical property :
• Tensile strength: 240MPa; yield strength: 170MPa; elongation rate: 24% (annealing state).
• Hardness: HV 120-200 (soft state as low as HV 100).
• Physical property :
• Density: 4.51g / cm³; melting point: 1668℃; thermal conductivity: 17W / (m · K) (20℃).
• Processing technic :
• Thermal working: forging temperature 700-850℃, final forging temperature 650℃ (avoid grain coarsening).
• Cold processing: the intermediate annealing (550-650℃) is required to restore the plasticity, and the cold rolling deformation rate is 40%.
• Welding: Argon arc welding (TIG) is recommended, welding tempering (550-650℃) to reduce residual stress.
Gr. 1 titanium profile, with its high plasticity, low density and corrosion resistance, is widely used in scenarios with strict performance requirements for molding performance, such as aerospace thin-wall parts, medical implant substrate, etc
