Stainless steel has important applications in the aerospace field, including:

Aircraft Structural Components

Fuselage frames, wing structures, landing gear components, etc. The high strength and good fatigue - resistance of stainless steel help ensure the stability and safety of aircraft structures.

Engine Components

Turbine blades, combustion chamber components, exhaust systems, etc. It can withstand the effects of high - temperature, high - pressure, and corrosive gas.

Hydraulic and Fuel Systems

Pipelines, connectors, valves, etc. The corrosion - resistance of stainless steel can ensure reliable operation in the environment of aviation fuel and hydraulic oil.

Fasteners

Bolts, nuts, etc. They maintain connection reliability in high - vibration and complex stress environments.

Spacecraft

Structures and components of satellites, rockets, etc. The resistance of stainless steel to space radiation and extreme temperature changes makes it suitable for the space environment.

Aero - engine Hot - end Components

Such as afterburners, tailpipes, etc., which require stainless steel to have high - temperature resistance and oxidation - resistance properties.

In conclusion, due to its excellent properties, stainless steel plays a key role in the aerospace field, providing important support for the reliability and performance of aircraft.
