Domestic standard: TA2 (GB / T 3620.1); international standard: Gr. 2 (ASTM B348).
Specification and parameters:
Plate: thickness 0.03-50mm (ultra-thin foil 0.03-0.8mm), width 610mm.
Pipe: outer diameter 3-500mm, wall thickness 0.2-30mm (seamless pipe pressure resistance is better).
Bar: 2-300mm diameter, surface polishing accuracy ± 0.05mm.
Surface preparation :
Annealing pickling (stress removal), sandblasting (Ra 1.6-3.2 μ m), mirror polishing (BA / 8K).
Criterion of detection :
Chemical composition analysis (titanium content and impurity control).
Mechanical properties test (tensile, impact), non-destructive testing (ultrasonic, penetration test).
Technical parameters
Mechanical property :
Tensile strength: 440-590MPa; yield strength: 373MPa; elongation: 20% (annealing state).
Hardness: HV 120-200; impact toughness: 30J / cm² (room temperature).
Physical property :
Density: 4.51g / cm³; melting point: 1668℃; thermal conductivity: 17W / (m · K) (20℃).
Processing technic :
Thermal working: the forging temperature is 700-850℃, and the final forging temperature is 650℃.
Cold processing: cold rolling deformation rate is 40%, and intermediate annealing (550-650℃) is required to restore plasticity.
Welding: Argon arc welding (TIG), welding tempering (550-650℃) reduces residual stress.
Gr. 2 titanium profile, with its high plasticity, corrosion resistance and biological safety, widely serves the high-end manufacturing and medical fields, and is a key material for both lightweight and reliability
