Free Forging Steel Block For Heavy Duty Hydraulic Cylinder Base Structure Components

This free-forged steel block is engineered specifically for the base structure of heavy-duty hydraulic cylinders, where outstanding strength, dimensional stability, and long-term reliability are essential. Produced through precision-controlled free forging, the block features a refined internal grain structure and superior metallurgical soundness, ensuring excellent resistance to high pressure, shock loads, and continuous cyclic forces commonly encountered in industrial hydraulic systems.

Product Features

• High Structural Integrity – Free forging delivers a dense, defect-free internal structure with improved mechanical properties compared with cast or fabricated blocks.

• Superior Load-Bearing Strength – Supports extreme hydraulic pressures and large bending forces, ideal for heavy-duty cylinder base assemblies.

• Enhanced Toughness & Fatigue Resistance – Optimized heat treatment ensures stable performance under continuous high-stress operating conditions.

• Dimensional Stability – Suitable for precision machining after forging, maintaining accurate tolerances for cylinder installation interfaces.

• Material Flexibility – Available in carbon steel and alloy steel grades such as 42CrMo, 45#, 20CrNi2Mo, and customized specifications.
