Nickel-based K403 Powder Description
Nickel-based K403 Powder is a cast nickel-based superalloy. The alloy has high-temperature strength. It is widely used for casting guide vanes and working blades of turbojet, turbo under, turboshaft, and turbofan series engines. The γ' phase is the main strengthening phase of nickel-based alloys and affects the high-temperature properties of the alloys. The K403 alloy has a higher content of γ' phase forming elements Al, Ti, etc., so the volume fraction of the γ' phase in the alloy structure is higher.

Nickel-based K403 Powder FAQs
Q1: What manufacturing processes use Nickel-based K403 Powder?
- Investment Casting: Commonly used to produce complex parts like turbine blades with precise dimensions and excellent surface finishes.
- Additive Manufacturing (3D Printing): Utilized in metal 3D printing processes such as Selective Laser Melting (SLM) and Electron Beam Melting (EBM) to create complex geometries for high-temperature applications.
- Powder Metallurgy: Used to press and sinter parts with intricate designs or special material requirements.
Q2: Why is Nickel-based K403 Powder ideal for turbine blades?
Turbine blades in jet engines and gas turbines must endure extreme temperatures and high mechanical stress. Nickel-based K403 Powder has:
- High thermal stability: Prevents structural degradation at elevated temperatures.
- Oxidation and corrosion resistance: Protects against damage from reactive gases and thermal cycling.
- Creep resistance: Ensures the blades maintain their shape and mechanical properties under prolonged stress.
Q3: How does Nickel-based K403 Powder compare to other superalloys?
Nickel-based K403 Powder offers superior high-temperature performance and oxidation resistance compared to many other superalloys, making it suitable for extreme environments. However, it may have specific trade-offs in terms of cost or machinability, depending on the application compared to other nickel-based superalloys like Inconel or Hastelloy.
