1. Key Properties
50CrMoV4 QT+Peeled is a high-performance, chromium-molybdenum-vanadium alloy steel that undergoes quenching and tempering (QT), followed by a peeling process to enhance surface finish and dimensional accuracy. This treatment ensures excellent hardness, tensile strength, and wear resistance, making it ideal for heavy-duty applications. It also exhibits good machinability and improved fatigue resistance, along with high impact strength, making it reliable in extreme loading and operating conditions.
2. Applications/Industries
Automotive: High-strength components such as gears, crankshafts, and axles that need to withstand heavy loads and resist wear.
Heavy Machinery: Critical parts like shafts, spindles, and springs, which are exposed to high stresses.
Tool Manufacturing: High-performance tooling and dies that require excellent wear resistance and toughness.
Oil & Gas: Pressure vessels, shafts, and other high-strength components for drilling and pumping equipment.
Power Transmission: Shafts, gears, and couplings in power systems exposed to harsh operating conditions.
Aerospace: Aircraft components such as turbine shafts and landing gear that demand high strength, fatigue resistance, and precision.
3. Certifications/Standards
