SCM440 alloy steel is a chromium-molybdenum low-alloy steel known for its high strength and excellent fatigue resistance, ideal for manufacturing mechanical components used under high-stress conditions. After quenching and tempering, SCM440 steel provides outstanding wear resistance and toughness, making it widely applied in gears, bolts, shafts, and transmission parts.
Following heat treatment, SCM440 steel can achieve a hardness of HRC28-32, with excellent impact resistance and wear properties. It also has good high-temperature resistance, maintaining stable strength and hardness in elevated temperatures, suitable for heavy-load and high-temperature mechanical components.
SCM440 alloy steel bar has good machinability, allowing for easy processing, and favorable weldability, making it suitable for complex structures and various manufacturing needs. It is widely used in the automotive and engineering machinery industries.
