Heat Treatment
Forging: The forging temperature of SAE 8620 structural steel should be between 925 ° C and 1230 ° C to avoid cracking and optimize the grain structure.
Normalizing: This step can refine the uneven cooling of the forging tissue after forging, usually at 900 ° C ~925 ° C, and cooled in still air.
Annealing: The complete annealing process is carried out at the nominal temperature of 820℃~850℃, and the furnace is cooled to room temperature.
Carburizing quenching and tempering: Carburizing, quenching and tempering treatment can significantly improve its surface hardness and wear resistance.
Application Areas of SAE 8620 Steel
Because SAE 8620 steel has the characteristics of high strength, high toughness and excellent wear resistance. So it is widely used in a variety of heavy machinery and equipment and automotive manufacturing industry, such as:
Heavy-duty vehicles: Manufacture key components such as transmission gear shafts.
Heavy-duty excavators, cranes: provide high-strength and high-toughness transmission components.
Machine tools: Manufacture of high load, high speed drive shaft and gear.
Aerospace: Manufacture of highly demanding aircraft and engine components.
Other fields: such as shipbuilding, trains, etc., are also commonly used to manufacture key components of this steel.
