High Strength Forged Cylinder for Hydraulic Press Piston Applications
Our High Strength Forged Cylinder is precision-engineered for use in hydraulic press piston systems, ensuring outstanding reliability and durability under extreme operating conditions. Manufactured from premium alloy steel through advanced open-die forging and heat treatment processes, this cylinder provides superior tensile strength, excellent impact resistance, and uniform internal structure.
Key features include:
Exceptional fatigue resistance for long service life in high-pressure environments.
Enhanced dimensional stability achieved through precision machining and controlled heat treatment.
Optimized grain flow ensuring consistent mechanical performance and reduced risk of failure.
Applications:
This forged cylinder is widely used in hydraulic presses, heavy-duty forming machines, metallurgical equipment, construction machinery, and marine hydraulic systems, where high compressive load and wear resistance are essential for safe and efficient operation.
| Item | Details (High Strength Forged Cylinder for Hydraulic Press Piston Applications) |
|---|---|
| Product Name | High Strength Forged Cylinder for Hydraulic Press Piston Applications |
| Material Grades | - 42CrMo4, 20CrNi2Mo, or 30CrNiMo8 – alloy steels with superior tensile strength, high hardenability, and toughness suitable for large-bore forged cylinders operating under continuous pressure cycles |
| Forging Equipment | - Hydraulic Presses & Open-Die Forging Hammers: 8T / 12T / 16T – ensuring deep deformation, fine grain refinement, and optimized internal structure for enhanced pressure resistance |
| Manufacturing Process | Raw Material Inspection → Preheating and Temperature Control → Open-Die Forging and Shaping → Normalizing → Quenching & Tempering (Q+T) → Precision Rough Machining → Ultrasonic and Dimensional Testing → Anti-Rust Coating and Packaging |
| Forging Ratio | ≥ 3.5 – ensures uniform grain flow along the cylinder axis, minimizes porosity, and enhances fatigue life under repeated piston strokes |
| Applications | - Hydraulic press piston cylinders and actuator housings - Forged cylinders for metallurgical forming equipment - Heavy-duty hydraulic systems in forging presses, injection machines, and marine machinery |
| Delivery Conditions | - Standard: Quenched and Tempered (Q+T) - Optional: Machined to specified bore tolerance, semi-finished, or as-forged according to assembly requirements |
| Testing & Inspection | - Chemical Composition: Optical Emission Spectrometry (OES) - Mechanical Testing: Tensile, Yield, Elongation, Hardness (HB/HRC) - Non-Destructive Examination: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional Accuracy: Bore concentricity, straightness, roundness, and surface finish verification |
Forged Steel Manufacturing Process:
Raw material verification → Precision cutting to required size → Controlled preheating under uniform temperature → Open-die or closed-die forging to specified geometry → Normalizing and heat treatment for grain refinement → Visual and dimensional inspection of forged blanks → Rough machining for shape accuracy → Non-destructive testing (UT, MT) and dimensional measurement → Quenching and tempering for enhanced strength and toughness → Final inspection of mechanical and surface quality → Finish machining to drawing tolerance → Dimensional verification and marking → Anti-rust coating, protective packaging, warehousing, and shipment.
