Is Zirconium A Good Metal?

The main material of zirconium bar is zirconium. It is a silvery-white transition metal with excellent properties such as high strength, high hardness, corrosion resistance, high temperature resistance and low neutron absorption cross section. Zirconium has a high melting point of 2128°C, good thermal conductivity and low thermal expansion coefficient, which makes the steel stable at high temperatures.

Special note, in the use of this steel, need to pay attention to the following points:

1.Prevent oxidation: zirconium is easy to react with oxygen at high temperature to generate oxides. Therefore, during processing and use, it is necessary to take appropriate protective measures to prevent it from being oxidized.

2.Avoid corrosion: although zirconium has excellent corrosion resistance, but in some strong acid, alkali or high temperature and high pressure environment, still need to pay attention to prevent its corrosion.

3.Correct storage: It should be stored in a dry, ventilated and non-corrosive gas environment to prevent it from moisture or other pollution.

Production Process | ASTM B351 Zirconium Bar

1.Pretreatment: necessary cleaning, descaling and cutting of raw materials are carried out to ensure the cleanliness of the surface of raw materials and the accuracy of the size.

2.Melting and casting

Smelting: The pretreated zirconium raw material is placed in a furnace protected by vacuum or inert gas and heated to above the melting point for smelting. The temperature and melting time should be strictly controlled in the melting process to avoid excessive impurities and pores.

Casting: Molten zirconium is poured into a pre-prepared mold and cast. Mold design needs to consider the shape, size and performance requirements of the product. Proper cooling rate should be maintained during the casting process to obtain good crystalline structure and properties.

3.Processing and molding

Roughing: Preliminary mechanical processing of cast zirconium bars, such as sawing, milling, etc., to remove excess parts and surface defects.

Finishing: Further fine processing of roughed steel, such as grinding, polishing, etc., is performed to obtain the desired shape, size, and surface finish.

4.Heat treatment

Annealing: The processed bar is annealed to eliminate the internal stress and improve the plasticity of the material during processing.

Solution treatment: For certain zirconium alloy rods with specific properties, solution treatment may be required to improve their strength and corrosion resistance.

5.Testing and inspection

Chemical composition analysis: Use spectrometer and other instruments to analyze the chemical composition of the product to ensure that it meets the requirements of the standard.

Physical properties testing: The zirconium rod is tested for its physical properties such as density, hardness and tensile strength to evaluate its quality.

Non-destructive testing: use ultrasonic, X-ray and other non-destructive testing means to detect its internal defects, to ensure that its internal quality is good.

Application Field Of Zirconium Bar

As a high-performance material, zirconium rod has excellent corrosion resistance, high temperature resistance and high strength, and is widely used in many fields:

1.Nuclear industry: Zirconium alloy bar is the preferred material for control rods and cladding in nuclear reactors due to its low neutron absorption cross section, good radiation resistance and excellent corrosion resistance.

2.Aerospace: In the aerospace sector, it is used in the manufacturing of high-temperature components such as engine blades, combustion chambers, etc., as it can withstand extremely high temperatures and pressures.

3.Chemical industry: Due to its corrosion resistance, zirconia is often used in the manufacture of reactors, heat exchangers, pipes and other components in chemical equipment, especially when dealing with highly corrosive media.

4.Medical devices: Due to its good biocompatibility and corrosion resistance, it also has applications in the field of medical devices, such as making dental implants and surgical instruments.

5.Jewelry: Zirconia is also used as a jewelry material, especially as one of the alternatives to diamonds, due to its high brightness and stability.
