Using extrusion method for die forging, there are two types: forward extrusion die forging and reverse extrusion die forging. Extrusion die forging can produce various sizes of titanium hollow bar blanks. Forgings with high geometric accuracy and denser internal structure can be obtained.
chemical composition, mechanical properties, ultrasonic testing.
Outer diameter (200-400) mm * Inner diameter (100-300) mm * Height (400-700) mm
Outer diameter (400-700) mm * Inner diameter (150-500) mm * Height (700-1500) mm
Outer diameter (700-1500) mm * Inner diameter (300-1200) mm * Height (40-600) mm
The inner and outer surfaces are polished, and the outer circle roughness Ra should not exceed 3.2um. The chamfer radius is 5-15mm
Titanium hollow rods have advantages such as compression resistance, high temperature resistance, and corrosion resistance. Low density (4.51KG/m3), high melting point (1660 ℃), high specific strength, good plasticity, widely used in industrial production such as aviation, aerospace, chemical, petroleum, medical, metallurgy, light industry, power, seawater desalination, ships, daily necessities, etc.
