GR12 titanium alloy is an α+β type titanium alloy containing iron, chromium, nickel, molybdenum, manganese, and other elements. In its composition, the iron content is 0.3~0.8wt%, which can improve the strength and fracture toughness of the alloy, and also has good corrosion resistance. Let's introduce the GR12 titanium alloy in all aspects.
1. Physical and chemical properties
GR12 titanium alloy has the characteristics of low density (4.51g/cm³), high strength, good plasticity, good corrosion resistance, and strong heat resistance. Therefore, it is widely used in aerospace, the chemical industry, medical equipment, and marine engineering. Its melting point is 1660℃, and its thermal expansion coefficient is low, which can be use in high-temperature environments.
2. Processing performance
GR12 titanium alloy can be easily processed by cold and hot processing. During processing, care should be taken to avoid excessive stretching, as GR12 titanium alloy may cause deformation and softening of the material. During processing, the wear of the material surface and the tool should be avoided, and the tool wear can be reduced by applying titanium alloy cutting fluid.
3. Corrosion performance
GR12 has good corrosion resistance and can withstand different chemical media, including acid, alkali, chloride ions, and seawater. When using, you need to pay attention to the surface finish of the material, because the rough surface is easy to cause pitting corrosion in harsh environments.
4. Welding performance
GR12 titanium alloy can be welded by a variety of methods, such as manual arc welding, TIG (argon arc welding), MIG/MAG (gas shielded welding), and light arc welding. Overheating should be avoided during welding, so pitting corrosion is prone to occur under high temperature stress.
5. Application range
Because GR12 titanium alloy has good corrosion resistance and high temperature strength, it is widely used in aerospace, chemical industry, medical equipment, marine engineering, automotive industry, shipbuilding, and other fields. For example, it can be used in oil, natural gas, and chemical processing equipment, missile vehicle-mounted structures, marine engineering pipelines and pump bodies, aviation fuselage parts, and medical implants.
In short, GR12 titanium alloy is a titanium alloy with excellent physical and chemical properties, processing properties, and corrosion properties, and is widely used in high-end fields. Understanding its properties and range of applications can help us better use and develop its potential.
