Hydraulic Press Systems Free Forging Cylinder Block 20CrMnTi
Free Forged Cylinder Block for Heavy-Duty Hydraulic Press Systems. Our free forged cylinder blocks are engineered for use in high-pressure, heavy-duty hydraulic press systems, delivering superior strength, dimensional integrity, and long service life under extreme working conditions. Forged from high-quality carbon or alloy steels, these blocks are designed to withstand high internal pressure and cyclic loading in forging, extrusion, and forming equipment.
Key Features:
-
Material Options: High-strength alloy steels (e.g., 42CrMo) and carbon steels (e.g., 45#) with excellent mechanical performance, pressure resistance, and machinability.
-
Forging Process: Precision open-die (free) forging to produce dense, defect-free blocks with refined grain structure and optimal strength in critical stress zones.
-
Dimensional Range: Customizable dimensions to suit hydraulic cylinder sizes from medium to ultra-large presses.
-
Heat Treatment: Quenching & tempering or normalizing options ensure improved hardness, toughness, and fatigue life in pressurized environments.
Applications:
-
Main cylinder blocks in hydraulic forging presses
-
Extrusion press cylinder housings
-
Heavy-load hydraulic systems in metallurgy, shipbuilding, energy, and forming equipment
