PRODUCT OVERVIEW
Our Leaf Spring 3 represents the pinnacle of suspension technology, engineered for commercial vehicles and heavy-duty applications. Manufactured from premium 52CrMnMoV spring steel, this component delivers exceptional load-bearing capacity and durability under the most demanding conditions.
MATERIAL SPECIFICATIONS
Constructed from high-performance 52CrMnMoV spring steel alloy, offering: – Superior fatigue resistance (1.5 million cycles at design load) – Excellent impact toughness (Charpy V-notch ≥35J at -20°C) – Optimal elastic properties for smooth ride quality – Consistent material properties across all production batches
MANUFACTURING PROCESS
Precision-engineered through advanced production methods: – Hot rolling process for optimal grain structure – Precision forging of critical stress points – CNC trimming for exact dimensional accuracy (±0.2mm tolerance) – Stress-relieving operations after forming
HEAT TREATMENT PROTOCOL
Comprehensive thermal processing ensures maximum performance: 1. Normalizing (880-920°C) for uniform microstructure 2. Annealing for machining stability 3. Oil quenching (830°C) for hardness 4. Tempering (420-480°C) for toughness Final hardness: HRC 36-40
