China Factory Direct | Compatible with 50+ Diesel Engines | Tensile Strength ≥600MPa

1. Core Advantages of QT600-3 Crankshaft

"Durable Power Core, Delivered Globally from China"

Material Excellence: Made of nodular cast iron QT600-3 with pearlitic matrix structure, achieving a tensile strength of ≥600MPa and excellent fatigue resistance. Notably, all products are SGS-certified for salt spray resistance (10-year corrosion protection), ensuring reliability in extreme environments like deserts or high humidity

Fast Global Delivery: Shipped directly from Shandong production base, supporting DDP/DAP logistics. Middle East/Africa orders typically arrive within 7-15 days via Shanghai/Shenzhen ports. Real-time tracking is available in English, Chinese, and Arabic.

2. Technical Specifications & Manufacturing Process

1. Chemical Composition & Mechanical Properties

2. Key Manufacturing Technologies

Heat Treatment Flexibility: Adjustable via quenching (930°C ×2h) and tempering (600°C ×2h) to enhance hardness (up to HV550) or plasticity (elongation ≥3%)

Laser Surface Hardening: Post-treatment achieves surface hardness of 49–60 HRC, with optimized parameters (1,600W power, 14mm spot diameter) ensuring uniform martensitic microstructure

Defect Control: Vacuum casting reduces porosity to ≤0.5%, lowering defect rates by 60%
