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.
| Item | Details |
| Product Name | 42CrMo4 Forged Cylinder for Hydraulic Presses and Port Equipment |
| Material Grades | - Alloy steel: 42CrMo4 (DIN 1.7225), ideal for high-load, high-pressure applications - Excellent balance of toughness, fatigue resistance, and hardenability |
| Forging Equipment | - Hydraulic Hammers & Presses: 5T, 8T, 12T - Capable of open die forging large cylindrical sections with uniform grain flow |
| Manufacturing Process | Material Inspection → Heating → Open Die Forging → Heat Treatment (Q+T) → Rough or Finish Machining → NDT → Dimensional Inspection → Packaging |
| Forging Ratio | ≥ 3.0 — Ensures directional fiber structure, reduced internal defects, and extended fatigue life under cyclic pressure loads |
| Applications | - Hydraulic press cylinders and piston sleeves - Drive cylinders for port lifting and gantry crane systems - Tubular forged parts for heavy-duty hydraulic and pneumatic systems |
| Delivery Conditions | - Standard: Quenched + Tempered (Q+T) - Optional: Normalized + Tempered, semi-machined, or as-forged upon request |
| Testing & Inspection | - Chemical Composition: Verified by Optical Emission Spectrometry - Mechanical Tests: Tensile strength, hardness, impact testing - NDT: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional Control: Full inspection of outer diameter, inner bore, and roundness |
