Ion Nitriding and Heat Treating Solutions for Aerospace Components

Sun Steel Treating proudly serves the cutting-edge aerospace industry with a complete range of metal heat treatment services and surface hardening solutions. Our aim is to provide higher quality, consistency, and reliability in the production of precision aerospace parts and tooling.

Through innovative metallurgical engineering processes such as ion nitriding, vacuum hardening, steel steam treating and stress relieving, Sun Steel delivers superior aerospace components to leading aviation providers throughout the nation.

Engineering Better Aviation Components with Ion Nitriding

Ion nitriding is commonly used in aerospace manufacturing applications to enhance the material properties of components. For example, the plasma nitriding process is often used in welding applications to reduce heat distortion and weld corrosion – both of which are imperative when it comes to the fabrication of precision aerospace parts. Other advantages for aviation productions include a more durable, wear-resistant tool surface, higher fatigue strength, and a lower coefficient of friction.

Sun Steel Treating’s trademarked Ionitriding® process is a method of surface hardening that produces nitrided cases for premium aviation components. The process uses glow discharge technology to release nitrogen ions that coat the surfaces of your aerospace tooling, thus optimizing the material properties to deliver higher performance and enhanced durability.

We perform this process in vacuum vessels at extremely low temperatures (750°-1040°F or 400°-560°C). This unique ion nitriding process can be applied to most ferrous metal components that are used in the manufacturing of aerospace products.

  • Increases resistance to wear, fatigue, and corrosion for your aerospace tooling and equipment.
  • Improves resistance to cracking, erosion, and corrosion to maximize the reliability and longevity of your aerospace tooling.
    • This is due to compressed stresses induced by the plasma nitriding process and the formation of hard, compacted nitrided layers. Sun Steel Treating achieves case depths up to 0.025″ or 0.6mm deep.
  • Lowers coefficient of friction (typical 0.10 against steel).
  • Advanced stress relieving properties are achieved within the same process.
