Material You Can Choose for Your Hydraulic Cylinders
ZHY selects materials to help ensure that your hydraulic cylinders possess exceptional strength, machining precision, and long-term stability.We choose material based it on your equipment’s operating pressure, load capacity, stroke length, and application environment.We can also using the materials you specify for your hydraulic cylinder fabrication.
The below details materials that you can choose for your hydraulic rams, including their grades, typical applications, and performance characteristics, suitable for a wide range of operating environments.
| Material & Grade | Typical Applications | Performance Characteristics |
| 20# / Q235 | Low-pressure hydraulic cylinders (Pressure ≤16MPa), light-duty equipment | Low cost, good weldability, suitable for low-load and non-harsh working conditions |
| 45# Steel | Medium-low pressure hydraulic cylinders (Pressure ≤20MPa), general-purpose equipment | Higher strength than Q235, can be tempered, strong versatility and cost-effectiveness |
| 27SiMn Alloy Steel | Medium-high pressure hydraulic cylinders (Pressure ≤31.5MPa), construction machinery | Excellent strength, toughness and weldability after quenching and tempering; most commonly used in engineering machinery cylinders |
| 42CrMo Alloy Steel | High-pressure/ultra-high pressure hydraulic cylinders (Pressure ≥31.5MPa), heavy-duty, mining, metallurgy | High strength, high toughness and impact resistance; suitable for harsh and heavy-load working conditions |
