The technical properties of 34CrNiMo6 steel include a high tensile strength, good toughness, and high fatigue strength. It is commonly used in applications requiring high strength and durability, such as heavy machinery, automotive components, and engineering equipment.
To enhance the durability and strength of 34CrNiMo6 steel, it undergoes a quenching and tempering process. This process involves heating the steel to a high temperature, followed by rapid cooling (quenching) and then reheating to a lower temperature to improve its toughness and ductility. This treatment also helps to increase the steel’s resistance to wear and fatigue, making it suitable for demanding applications.
