Which material is often used for hydraulic cylinder construction?

High-strength steel is commonly used for hydraulic cylinder construction due to its superior mechanical properties, including high tensile strength, durability, and resistance to deformation under heavy loads. Hydraulic cylinders are subjected to significant pressures and forces during operation, and the materials used must withstand these stresses without failing.

High-strength steel provides the necessary structural integrity and fatigue resistance, making it ideal for the rigorous demands placed on hydraulic components. While other materials like aluminum and sometimes specific plastics may be used in less demanding applications or in specific designs, high-strength steel remains the preferred choice for most hydraulic cylinders where performance and safety are critical.
