High-Strength Steel Alloy in Aeronautics
30NCD16 (or 1.6755) is a steel alloy containing chromium, nickel, and molybdenum. It is comparable to other steels like 35NCD16, which shares a similar chemical composition and mechanical properties but is optimized for specific uses. Like 35NCD16, 30NCD16 is often used in the aerospace and automotive industries for components requiring high strength and durability under fatigue and impact, such as gears, turbine rotors, and fasteners.
This steel alloy can undergo various heat treatments to enhance its mechanical properties: annealing, quenching, and tempering. Annealing aims to reduce hardness and improve machinability, while quenching and tempering increase hardness and mechanical strength.

How 30NCD16 is used in aerospace
The practical applications of this steel in aircraft construction.
Turbine rotors
Turbine rotors are present in Auxiliary Power Units and provide the necessary energy for the aircraft when it is on the ground. The wear resistance provided by 30NCD16 is suitable for rotors that spin very rapidly.
Gears
Gears enable the movement of flaps and landing gear. Subjected to constant friction, they must be wear-resistant: this is where the use of 30NCD16 comes in.
Fasteners
Fasteners (bolts, screws, etc.) maintain the structural integrity of aircraft, subjected to various load and stress conditions. 30NCD16 is particularly suitable here, making them resistant to impacts and vibrations.
