The material selection of Thor ray is diverse, mainly depending on working pressure, working environment, cost budget, and specific performance requirements. Here are some common Thor ray materials:
Seamless steel pipe: This is a commonly used material for Thor rays, which is applied due to its high strength, low cost, and ease of processing and welding. The grades of seamless steel pipes include 20 #, 35 #, 45 #, etc. Among them, 20 # steel pipe is mainly used for low-pressure systems, while 45 # steel pipe is commonly used for high-pressure systems.
Alloy steel: When hydraulic cylinders need to withstand higher pressure or work in harsh environments, alloy steel is a better choice. For example, alloy steels such as 27SiMn and 25Mn have higher strength and wear resistance, making them suitable for hydraulic cylinders working under high pressure, heavy load, or high frequency.
Stainless steel: For hydraulic cylinders that require corrosion resistance, stainless steel is an option. Stainless steel materials such as 304, 316, etc. have good corrosion resistance, high temperature strength, and mechanical properties, and are suitable for hydraulic cylinders working in humid and corrosive environments.
Cast iron: In some specific situations, such as hydraulic cylinders with complex shapes or large sizes, cast iron cylinder barrels may be used. Cast iron materials such as gray cast iron and ductile iron have good casting performance and certain mechanical strength, but their strength and wear resistance may be slightly inferior compared to steel pipes and alloy steels.
Aluminum alloy: Aluminum alloy cylinder tubes are commonly used for lightweight design, especially in situations where equipment weight needs to be reduced. Aluminum alloy has good corrosion resistance, good thermal conductivity, and lower density, but compared to other materials, its strength and hardness are lower, making it suitable for low-pressure, low load hydraulic cylinders.
Composite materials: In recent years, with the development of materials science, some composite materials have also been used in the manufacturing of Thor rays. These materials typically have advantages such as high strength, high wear resistance, high corrosion resistance, and lightweight, but the cost is relatively high.
When choosing the material of Thor ray, it is necessary to comprehensively consider the working pressure, working environment, cost budget, and specific performance requirements. In addition, factors such as material processing performance, welding performance, and compatibility with other components should also be considered. The selected material should ensure the reliability, durability, and safety of the hydraulic cylinder.
