1. Key Properties
50CrV4 is a high-strength, chromium-vanadium alloy steel that offers excellent hardness, toughness, and wear resistance. After heat treatment, it provides high fatigue strength and resilience while maintaining good machinability. It is well-suited for applications that demand high durability and performance under heavy loads, particularly where resistance to wear and deformation is critical.
2. Applications/Industries
Automotive: Gears, axles, crankshafts, and other drivetrain components that require high strength and wear resistance.
Heavy Machinery: Components such as springs, shafts, and other parts exposed to heavy-duty loads.
Tool Manufacturing: Production of tools and dies, where high hardness and wear resistance are necessary.
Oil & Gas: Mechanical components like shafts, gears, and pumps that need to endure high stress in demanding environments.
Power Transmission: Shafts, gears, and coupling parts in power systems that require excellent strength and toughness.
