Product Introduction
H9 Hydraulic Cylinder Steel Honed Tube is made of high-quality steel by cold drawing. Its interior is precision honed, with extremely high dimension accuracy and surface finish. This tubing can effectively reduce friction loss in the hydraulic system, improve energy transfer efficiency and ensure the system operates smoothly and reliably. It's widely used in various high-performance hydraulic equipment.
Product Advantages
High-Strength Material for Durability
H9 Hydraulic Cylinder Steel Honed Tube uses high-strength alloy steel (ST52, Q345B) with uniform hardness from quenching and tempering. It maintains deformation resistance across 4mm-100mm outer diameters, even at 0.4mm wall thickness, handling continuous high-pressure impacts in mining equipment. Wear resistance exceeds standard carbon steel tubes by 2X, significantly extending maintenance cycles.
Precision Honing for Sealing Performance
Cold rolling and honing deliver mirror-smooth inner walls, preventing piston seal damage from 0.4mm to 40mm wall thicknesses. Combined with seamless tube straightness, it minimizes oil leakage, increasing seal life by 40%-ideal for precision machinery requiring long-term stability.
Multi-Layer Coating for Corrosion Resistance
Chemical nickel plating and passivation create dense protective layers on 4mm-100mm tubes. Resistant to saltwater, acids, and alkalis, it ensures over 8 years of service in humid conditions-3X longer than standard coatings.
Cold Rolling Ensures Dimensional Accuracy
Cold-rolled H9 tubes maintain industry-leading outer diameter tolerance and under 5% wall thickness variation. From 5.8m to 12m lengths, they withstand -40°C to 200°C without deformation or bursting under high pressure.
Custom Sizing Reduces Waste
Available in 4mm-100mm outer diameters, 0.4mm-40mm walls, and 5.8m-12m lengths (cut-to-size). Customization achieves 98% material utilization, cutting processing costs by 20% and fitting specialized equipment like excavators and injection molders.
