BT3-1 Titanium Bar details
Chemical Composition
The nominal chemical composition of BT3-1 Titanium Alloy is: Ti-6Al-1.5Cr-2.5Mo-0.5Fe-0.3Si, with aluminum content of 5.5-6.75%, vanadium content of 2.5-3.3%, molybdenum content of 1.8-2.4%, iron ≤0.30%, oxygen ≤0.15%, nitrogen ≤0.05%, carbon ≤0.08%, and hydrogen ≤0.015%.
This alloy exhibits superior mechanical properties: annealed tensile strength ≥980MPa, yield strength ≥825MPa, elongation ≥10%, and density of 4.45g/cm³, approximately 40% lighter than steel. Its high-temperature resistance is outstanding, allowing for long-term operation at 400-450℃ and short-term withstand of 600℃.
Standards Execution
BT3-1 Titanium Rods conform to GB/T 2965-2017 standard, corresponding to ASTM B348. A complete range of specifications is available, with diameters ranging from Φ10mm to Φ350mm and lengths up to 6000mm, meeting diverse application requirements.
Application Areas
Aerospace Industry
Primarily used in critical load-bearing components such as compressor blades, discs, and fasteners for aero-engines. Its lightweight, high strength, and high-temperature resistance make it a preferred material for aerospace structures.
Industrial Applications
Used in marine engineering applications such as submarine pressure hulls and propeller shafts, exhibiting excellent resistance to seawater corrosion. Also used in chemical equipment for manufacturing corrosion-resistant pipes, valves, and other components.
Medical Industry
After biocompatibility treatment, it can be used to manufacture medical implants, bone grafts, and other medical devices.
Processing and Heat Treatment Processes
The hot working temperature of BT3-1 titanium rods is controlled within the α+β two-phase region at 850-950℃ to avoid overheating in the β phase region, which could lead to grain coarsening. Cold working requires intermediate annealing. Welding can be done using arc welding or electron beam welding, and post-weld annealing is necessary to relieve stress.
Heat treatment processes include:
• Annealing: Holding at 750-850℃ for 1-2 hours, then air cooling.
• Strengthening treatment: Solution treatment (900-950℃) + aging (500-600℃), which can further improve strength.
Production and Quality Control
BT3-1 titanium rods are produced using a vacuum consumable arc furnace for melting, with at least two melting cycles to ensure material purity. The production process strictly controls chemical composition and impurity content, and product quality is ensured through non-destructive testing such as ultrasonic testing.
With its excellent comprehensive performance and broad application prospects, BT3-1 titanium rods have become an indispensable key material in modern high-end manufacturing, playing a vital role in promoting technological progress and industrial upgrading.
