BT20 Titanium Plate

BT20 titanium plate is one of the titanium plates produced by our company. We can also process and customize other various titanium alloy semi-finished and finished materials and commodities for you. BT20 is a near-α-type titanium alloy, and solid-solution strengthening through the α-stabilizing element Al is the main strengthening mechanism of this alloy. Neutral elements Zr and β-stable elements Mo and V are added to the alloy to improve processability. The Al equivalent of the alloy is 6.58%, which belongs to a near-α-type titanium alloy with a high Al equivalent, so it not only has good heat strength and weldability of an α-type titanium alloy, but also has a process plasticity close to that of an α-β-type titanium alloy. . The alloy has moderate room temperature and high temperature strength, good thermal stability and weldability.

1. BT20 titanium has high strength, which is due to the excellent yield strength and tensile strength of titanium alloy, which makes it have good endurance and strength under high-strength and high-temperature environments. Therefore, it has become the material of choice for manufacturing high-end equipment such as aircraft, missiles, and ships.

2. BT20 has excellent corrosion resistance and can adapt to the requirements of different environments. It can be used for a long time without being corroded in harsh environments such as seawater, strong acid, and strong alkali, so as to ensure that the equipment maintains good working results and performance for a long time. Therefore, it is widely used in industries such as chemical industry, marine and oil extraction.

3. BT20 titanium has good plasticity and can be processed by various methods such as hot processing and cold processing. Due to the plasticity of titanium alloy, it can be processed into various shapes, such as plates, pipes, etc., which is very suitable for the production of medical equipment, sports equipment and other fields.

The hardness HB(d) of this brand after annealing is 3.3~3.6 , the tensile strength is 900MPa~1130MPa, the tensile strength at 500°C is 570MPa, and can be kept at 470MPa for 50h continuously, and the material density is small and the specific strength is high. , Excellent corrosion and oxidation resistance. Those that meet the above properties can be selected.

BT20 alloy titanium can be produced by various melting and casting techniques such as vacuum arc remelting (VAR), plasma arc melting (PAM), electron beam melting (EBM) and powder metallurgy (PM). VAR is the most common method for producing BT20 titanium plate, which is known for producing materials with high purity, low pollution and excellent mechanical properties.

BT20 titanium plate usually undergoes a heat treatment system, including annealing, solution treatment and aging.

1. The annealing process is used to relieve any stress in the material that may have developed during processing. This is achieved by heating the material to a specific temperature for a certain period of time, and then slowly cooling the material to room temperature.

2. The solution treatment process involves heating the material to elevated temperatures for a period of time to dissolve any secondary phases that may have formed during processing. The material is then cooled to room temperature at a controlled rate.

3. The final step in the heat treatment system is aging, which involves heating the material to a specific temperature for a specified period of time to promote the precipitation of secondary phases and achieve the desired mechanical properties.

BT20 titanium alloy has been widely used in the manufacture of load-bearing structural parts of aircraft and engines, especially welded load-bearing structural parts. This grade is used to produce non-standard parts with high temperature requirements, such as non-standard flower nuts, plugs, linings Sleeves, ball joints, pressure plates, hook pins, screw plugs, plugs, pipe joints, elbow joints, etc.

BT20 alloy in our company include thin plate, thick plate, rolled bar, forged bar, die forging, forging, extruded profile, welded ring piece, integral ring rolled piece and casting .
