Talk about the importance and selection of hydraulic cylinder barrel material

The cylinder barrel of the hydraulic cylinder is one of its core components, which directly affects the performance, life and safety of the cylinder. Choosing the right cylinder barrel material is important to ensure the stable operation of the hydraulic system.

Commonly used materials

1, seamless steel pipe: one of the commonly used cylinder material, with good mechanical properties and processing performance, suitable for most working conditions. Common materials are 20# steel and 45# steel.

2, high-strength alloy steel: such as 40Cr, 35CrMo, etc., with higher strength and wear resistance, suitable for high-pressure and heavy-duty occasions.

3, stainless steel: used in corrosive environments, such as food industry, chemical industry, etc., commonly used stainless steel materials are 304 and 316.

Material selection based on

1, working pressure: high-pressure applications need to choose high-strength materials, such as alloy steel; low-pressure applications can choose ordinary carbon steel or stainless steel.

2, the working environment: consider the temperature, humidity, corrosivity and other factors. For example, in a humid or corrosive media environment, stainless steel is the better choice.

3, cost: according to the budget to choose the right material, while taking into account the performance and durability.

In short, choosing the right hydraulic cylinder barrel material is the key to ensure the long-term stable operation of the equipment. According to the specific working conditions and requirements, the comprehensive consideration of material performance, cost and other factors in order to make a good choice.
