Transmission gears: AISI5120 alloy steel is commonly used in the manufacture of automotive transmission gears. Due to the high loads and frequent movements of the transmission gears, the durability and reliability of the materials are required. AISI5120 alloy steel has high hardness and wear resistance, which can meet the needs of transmission gears in the working process.
Crankshaft: The crankshaft of an automobile engine is one of the key components, which bears the rotational power and reciprocating motion of the engine. The wear resistance and strength of AISI5120 alloy steel make it ideal for use in the manufacture of crankshafts, ensuring the reliability and durability of the engine.
Piston pins: Piston pins are the key parts that connect the piston and the connecting rod and are subjected to high temperature and high pressure operating conditions. AISI5120 alloy steel provides sufficient hardness and wear resistance to ensure the safety and reliability of piston pins in these harsh environments.
To sum up, AISI5120 alloy steel is widely used in auto parts manufacturing due to its high hardness and wear resistance. It is suitable for manufacturing transmission gears, crankshafts, piston pins and other parts that require durability and reliability to ensure the performance and service life of the car.
