  • Specific Application Aisi 4140 Mechanical Steel Different Manufacturing Fields - China

    price: 157.00 Dollar US$

    AISI 4140 mechanical steel is a medium carbon alloy structural steel that is widely used in a variety of mechanical manufacturing scenarios due to its good comprehensive properties, such as high strength, toughness, wear resistance and hardenability.

    Mechanical transmission parts

    Gears: Gears are key components in mechanical transmission and need to have high hardness, wear resistance and fatigue resistance.

    After carburizing or quenching, AISI 4140 mechanical steel can achieve a high level of surface hardness while maintaining the toughness of the core, which can effectively withstand meshing forces and impact loads.

    Shaft parts: Such as motor shafts, reducer shafts, etc., these parts need to withstand high torque and bending stress.

    The high strength and good hardenability of AISI 4140 mechanical steel enable it to meet these requirements, while its toughness can prevent parts from breaking under high stress.

    Bolts and nuts: High-strength bolts and nuts need to have good tensile strength and toughness to ensure the reliability of the connection.

    After heat treatment, AISI 4140 mechanical steel can achieve the required balance of strength and toughness, and is suitable for manufacturing high-strength fasteners.
