The use of stainless steel belt in rail transit is mainly based on its advantages in corrosion resistance, high strength, good processing performance, fire resistance and beautiful appearance. The following is a detailed introduction:
1. corrosion resistance: the operation environment of rail transit is complex, and vehicles may face a variety of corrosion factors such as humidity, salt spray, chemical substances, etc. The stainless steel belt has excellent corrosion resistance, which can resist the erosion of rainwater, groundwater, acid and alkali substances in the air, reduce the damage and potential safety hazards of vehicle structure caused by corrosion, and extend the service life of the vehicle. For example, the stainless steel strip can effectively prevent the rust and corrosion of the vehicle shell and key components in the subway, light rail, etc. operating in coastal areas or in a humid environment.
2. high strength and lightweight: the stainless steel belt has high strength and can withstand various stresses and impact forces during vehicle operation to ensure the stability and safety of vehicle structure. At the same time, compared with some traditional metal materials, the density of stainless steel is relatively small, and the use of stainless steel belt can realize the lightweight of the vehicle on the premise of meeting the strength requirements. Lightweight is very important for rail transit vehicles. It can reduce energy consumption, reduce rail wear, and improve vehicle operation efficiency and performance.
3. good processing performance: the stainless steel strip is easy to process and form, and can be made into parts of various shapes and sizes through rolling, bending, stamping, welding and other processing processes, so as to meet the design requirements of different parts of rail transit vehicles. For example, the vehicle body frame, door, seat frame and other components can be processed with stainless steel strips, which can realize complex structural design and improve the overall beauty and practicability of the vehicle.
4. fire protection performance: stainless steel has good fire protection performance. In case of fire, the stainless steel belt will not burn or release toxic gases as quickly as some plastics or composite materials, which can win more escape time for passengers and rescue personnel and reduce the harm of fire to personnel and vehicles. This is of great significance to ensure the safe operation of rail transit.
5. beautiful appearance: the stainless steel strip has a smooth, clean surface and metallic luster, which can provide a beautiful appearance for rail transit vehicles. After polishing, wire drawing and other surface treatments, the stainless steel belt can present different textures and effects, improve the overall image and quality of the vehicle, and meet the requirements of modern urban rail transit for vehicle appearance design.
