Forged Turbine Disks for Aerospace: Reliable Core Components Under Extreme Conditions

Quick Answers

Why Forged Turbine Disks Are the "Core Choice" for Aero-Engines

1. Resistance to extreme conditions: Can withstand 1500℃ high temperature + 20G centrifugal force, with 40% higher fatigue resistance than cast parts;
2. Material uniformity: Isothermal forging ensures complete metal flow lines, avoiding local stress concentration;
3. Compliance: Full batch traceability, meeting the strict standards of AS9100D for aerospace components.
   
   
   According to International Forging Group (2024) data, 90% of aero-engine turbine disks use forging—its failure risk within a 5000-hour flight cycle is close to zero.

Procurement & Integration Recommendations

1. Material Traceability: Request complete heat lot and chemical composition reports to confirm the nickel content (50-55%) of GH4169;
2. Non-Destructive Testing: X-ray + ultrasonic flaw detection are mandatory to eliminate internal defects;
3. Storage Requirements: Store in a temperature-controlled (20±5℃) dry environment to prevent hydrogen embrittlement.
