Description

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


Item Details
Product Name Free Forging Steel Block for Heavy Duty Hydraulic Cylinder Base Structure Components
Material Grades - Alloy steels such as 42CrMo, 45#, 18CrNiMo7-6,20CrNi2Mo — selected for high tensile strength, excellent toughness, and superior wear resistance- Materials optimized to withstand high-pressure hydraulic loads and repetitive cyclic stresses
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T — suitable for forging thick-section steel blocks- Open-die forging presses (up to 3600T) — ensures dense, uniform grain flow and defect-free internal structure- Specialized tooling for precise block geometry and machining allowances
Manufacturing Process Raw material inspection → Controlled preheating → Free forging (block shaping) → Heat Treatment (quenching + tempering) → Intermediate quality checks → Rough machining of critical surfaces → Non-destructive testing (UT, MT) → Final dimensional inspection → Protective packaging
Forging Ratio ≥ 3.0 — Promotes aligned fiber structure, high fatigue resistance, and superior mechanical integrity under high-pressure hydraulic operations
Applications - Base components of hydraulic cylinders in heavy construction machinery (excavators, loaders, piling rigs)- Industrial hydraulic presses and forming machines- Hydraulic systems in port handling equipment and lifting units- Mining, metallurgical, and oil & gas high-pressure hydraulic equipment
Heat Treatment Options - Quenched + Tempered — Achieves high load-bearing capacity and core toughness- Optional stress relieving for improved dimensional stability- Surface treatments available to enhance wear resistance and prevent corrosion
Testing & Inspection - Chemical: Spectrometer analysis for alloy verification- Mechanical: Tensile, yield strength, hardness, and impact toughness tests- Non-destructive testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT)- Dimensional: Verification of block height, width, bore positions, and flatness
Value-Added Services - Precision machining of mounting surfaces, bolt holes, and cylinder interfaces- Surface finishing such as shot blasting, painting, or anti-corrosion coating- Export-quality packaging for overseas shipping- Full traceability: heat number, batch number, and certified mechanical & NDT reports
