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.

Application Fields

• Hydraulic cylinders for heavy construction machinery – excavators, loaders, dozers, piling rigs

• Industrial hydraulic presses and forming machinery

• Port and lifting equipment hydraulic systems

• Mining and metallurgical equipment requiring high-pressure cylinder bases

• Oil & gas hydraulic power units and actuator assemblies

Steel Forging Production Flow

Steel ingots are inspected and stored → Cut to size → Heated under controlled conditions → Forged and heat-treated → Preliminary blank inspection → Rough machining → In-process quality checks (UT, MT, dimensional, hardness) → Quenching and tempering → Post-heat-treatment inspection → Finish machining → Final dimensional check → Marking, packaging, and storage for shipment.
