42CrMo4 Forged Cylinder for Hydraulic Presses and Port Equipment

42CrMo4 Forged Cylinder for Hydraulic Presses and Port Equipment.

Our 42CrMo4 forged cylinders are specifically engineered for high-pressure and heavy-load applications such as hydraulic presses and port handling equipment. Produced through open die forging and followed by precision heat treatment, these cylinders offer excellent tensile strength, impact toughness, and fatigue resistance. Their uniform grain flow and enhanced structural integrity ensure reliable performance under continuous stress, making them ideal for mission-critical components in harsh industrial environments.

Key Features:

• Material Grade: 42CrMo4 (DIN 1.7225), known for superior strength and hardenability

• Forging Method: Open die forging with ≥3.0 forging ratio for enhanced grain structure

• Heat Treatment: Quenched and tempered (Q+T) for improved mechanical performance

• High Load Capacity: Ideal for dynamic and high-pressure systems

• Excellent Machinability: Suitable for deep boring, honing, and custom flange machining

• Size Range: 100 to 7000 kg

Application Fields:

• Hydraulic Presses: Cylinder housings, piston sleeves, press columns

• Port Equipment: Lift system cylinders, gantry crane drive modules

• Heavy Machinery: Forged casings for hydraulic and pneumatic power units

• Energy Sector: Pressure-retaining forged parts for turbine and compressor systems

• Offshore & Marine: Load-bearing tubular components for jack-up rigs and hoisting systems
