FAQs

Why is stainless steel used for aerospace engine components?
Stainless steel provides the necessary strength, corrosion resistance, and heat resistance to withstand the extreme mechanical stress and high temperatures characteristic of aerospace environments.

How does CNC machining improve the precision of stainless steel parts?
Advanced multi-axis CNC machining, such as 5-axis milling and precision grinding, allows for ultra-tight tolerances (up to ±0.002mm) and complex geometries with exceptional repeatability that manual machining cannot match.

Which stainless steel alloys are most suitable for aerospace engine parts?
SUS17-4PH is highly valued for its fatigue resistance in rotors, while SUS316 and SUS304 excel in corrosion resistance for engine housings and fasteners. SUS440C is the ideal choice for wear-resistant bearings.

What surface treatments enhance the durability of stainless steel in aerospace engines?
Treatments like electropolishing, passivation, PVD coating, and chrome plating significantly improve surface smoothness, surface hardness, and long-term corrosion resistance.

What prototyping methods are best for stainless steel components in aerospace applications?
CNC machining prototyping provides the most accurate reflection of the final product's mechanical properties, while Rapid Molding and 3D printing offer quick-turnaround alternatives for initial design validation.
