Product Description
Detailed Specifications & Features
65Mn Waved Spring - High Elasticity for Precision Machinery Applications
65Mn high-carbon spring steel stands as a premier material for waved springs, renowned for its exceptional mechanical properties that make it ideal for precision engineering. As an elastic element with precisely formed peaks and valleys on a metal ring, our 65Mn waved spring delivers a unique combination of high elasticity, impact resistance, and load stability—critical for applications demanding controlled deformation and reliable axial preload.
Core Material Advantages
65Mn steel (chemical composition: 0.62-0.70% C, 0.90-1.20% Mn) is engineered to provide:
- Superior Elasticity: Tensile strength up to 1,200 MPa and yield strength of 1,000 MPa, enabling rapid shape recovery after deformation and maintaining stable force output under cyclic loads
- Exceptional Fatigue Resistance: Withstands over 10⁶ load cycles without performance degradation, making it suitable for dynamic precision machinery applications like CNC spindle bearings and robotic arm joints
- Optimal Stiffness Control: Designed for small-load (5N-300N) and low-deformation (≤0.03mm) scenarios, providing consistent axial preload to minimize component play and enhance equipment accuracy
Precision Machinery Applications
Our 65Mn waved springs are widely integrated into high-precision systems, including:
- CNC Machine Tool Spindles: Maintain bearing preload to reduce vibration and ensure machining accuracy (tolerance ±0.001mm)
- Semiconductor Wafer Handling Equipment: Provide gentle, consistent force to prevent substrate damage during transfer
- Medical Imaging Devices: Ensure stable component alignment in MRI and CT scanners, where micro-movement can compromise image quality
Customization & Surface Treatments
SUNZO offers comprehensive customization to meet unique application requirements:
- Dimensional Flexibility: Standard single-layer closed designs (diameters 6mm-300mm) and non-standard configurations (multi-layer, tapered profiles) with CNC-formed precision (±0.02mm tolerance)
- Surface Enhancement:
- Phosphating: Forms a crystalline protective layer, achieving 500+ hours of salt spray resistance (ASTM B117) and reducing friction by 25% for smooth operation
- Blackening: Creates a uniform Fe₃O₄ layer (5-8μm thickness) to enhance rust resistance and surface hardness (HV 450-550), ideal for cleanroom environments
Quality Assurance
Each 65Mn waved spring undergoes rigorous testing:
- Load-Deflection Validation: Ensures force tolerance within ±3% across the operating range
- Metallographic Inspection: Verifies uniform grain structure and heat treatment quality (quenched at 820-840°C, tempered at 480-520°C)
- Compliance: Meets ISO 9001 standards, with full material traceability documentation for critical precision machinery applications
Whether for standard or custom solutions, SUNZO's 65Mn waved springs combine material science and precision engineering to deliver reliable performance in the most demanding precision machinery environments.
