Kg & pieces - No decimal places. 12NC12 steel (or 13Nicr 12) is commonly used in aviation for parts that need to withstand variable loads while being subjected to friction. These parts must therefore ensure good wear resistance, also known as abrasion resistance. The 12NC12 alloy in its carburized form has a hardened upper layer that makes it suitable for this type of use. In its non-carburized form, it is used for mechanical parts that do not particularly require wear resistance related to abrasion. The variations in its chemical composition for aerospace.

The 12NC12 alloy is used in the composition of certain airplane parts, such as axles. These axles support and transmit loads between the wheels and the structure of the aircraft: landing gear axles, wheel axles, or differential axles. In the landing gear itself, 12NC12 steel is also used for the rack. Located near the hydraulic actuators, this gear mechanism allows the landing gear of an airplane to be deployed or retracted. In helicopters and some propeller-driven airplanes, the drive shaft connects the engine to the propeller(s): it passes through the firewall to reach the cabin. 12NC12 alloy provides it with good friction resistance.
