Aerospace industry demands materials that can withstand extreme conditions and provide high reliability. Special steel is one such material that is widely used in aircraft and spacecraft. The following are the steel grades that are suitable for aerospace purposes along with their specific characteristics:
1. Stainless Steel: Stainless steel is a corrosion-resistant steel that is widely used for essential aerospace components such as engine components, fasteners, and landing gear. It is essential to use stainless steel for these components as they are exposed to extreme temperature, pressure, and environmental conditions.
2. Tool Steel: Tool steel is an alloy steel that is used in the aerospace industry for manufacturing cutting tools, molds, and dies. It has excellent resistance to heat, wear, and shock, making it a reliable material for extreme working environments.
3. Titanium Alloys: Titanium alloys offer exceptional strength-to-weight ratio, making them an ideal material for aerospace applications. They are used in aircraft frames, landing gear, and turbine engines. Titanium alloys have excellent corrosion resistance, fatigue strength, and fracture toughness, making them a popular choice for aircraft components.
4. Nickel Alloys: Nickel alloys are used in aerospace applications where high-temperature resistance is required. They have excellent strength and corrosion resistance, making them ideal for gas turbine engines, rocket motors, and heat exchangers.
5. Carbon Steel: Carbon steel is used in the aerospace industry for manufacturing structural components. It is a high-strength and low-cost material that offers excellent mechanical properties. Carbon steel is used for making landing gear, engine mounts, and wing spars.
