Stainless steel cylinder barrels are engineered from alloys (e.g., 304, 316L, 316Ti, 904L) that combine high strength with exceptional resistance to corrosion, oxidation, and chemical attack. Unlike carbon steel or aluminum alternatives, they maintain structural integrity in harsh environments, resist pitting, and require minimal maintenance. This makes them ideal for applications where contamination control, hygiene, or exposure to caustic substances is critical.
Special Applications of Stainless Steel Cylinder Barrels
Marine & Chemical Handling Systems
Marine environments (saltwater, humidity) and chemical processing plants (acids, solvents) demand materials that resist chloride-induced pitting and oxidation. Stainless steel cylinder barrels, such as 904L (a super-austenitic alloy) or 316Ti (titanium-stabilized), thrive here:
- Saltwater Resistance: 904L resists pitting in seawater, making it ideal for hydraulic systems in ships, offshore rigs, and desalination plants.
- Chemical Resistance: 316Ti withstands sulfuric acid (up to 5% concentration) and phosphoric acid, critical for chemical transfer pumps and reactor agitators.
High-Precision Industrial Automation
In robotics, CNC machines, and precision assembly lines, cylinder barrels must deliver consistent performance over millions of cycles. Stainless steel’s low friction coefficient and dimensional stability make it a top choice:
- Wear Resistance: High-carbon grades (e.g., 304H) maintain surface hardness, reducing wear in high-load applications.
- Thermal Stability: Retains strength from -200°C to 600°C, suitable for aerospace automation and thermal processing equipment.
Stainless Steel Cylinder Tube Advantages
1. High precision tolerances; Wuxi YUTONG’s stainless steel cylinder tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.
2. Seamless tube with high pressure resistance;We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.
3. Advanced manufacturing equipment and facilities, including: cold drawing machine, cold rolling machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, cutting machine, etc.
4. High Smooth inside surface; The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).
