Key Technical Features Of ST52 Hydraulic Precision Tube
1. Superior Mechanical Properties
Achieved through quenching and tempering (Q&T) or cold drawing processes for high load-bearing capacity and fatigue resistance. Excellent ductility ensures minimal deformation under cyclic stress.
2. Precision Manufacturing
Precision cold-drawn or CNC-machined to tight tolerances for seamless integration into hydraulic systems. Guaranteed concentricity and roundness (per ISO 2768 Class 1).
3. Corrosion Resistance
Optional surface treatments: zinc plating, galvanization, or powder coating for enhanced resistance in humid or corrosive environments.
4. Hydraulic Compatibility
Smooth inner surface reduces friction loss, ensuring efficient fluid flow. Compatible with common hydraulic fluids (e.g., ISO VG 32, 46, 68).
5. Quality Assurance
100% non-destructive testing (NDT): Helium leak testing, ultrasonic inspection, or eddy current testing. Material certificates (EN 10204 3.1) and third-party testing reports available.
