42CrMo High-Strength Alloy Steel for Heavy-Duty Components

High-load Mechanical Parts

• Typical Applications: Heavy-duty gears, drive shafts, crankshafts, connecting rods, bolts, etc.

• Reason: High tensile strength (≥1000 MPa) and impact resistance, suitable for bearing alternating loads.

Wear-resistant Tools and Molds

• Typical Applications: Stamping molds, cold heading molds, cutting tools, rollers.

• Reason: Vanadium enhances surface hardness and wear resistance, ideal for high wear environments.

Aerospace and Automotive Industry

• Typical Applications: Aircraft landing gear components, engine connecting rods, transmission gears.

• Reason: Maintains strength at high temperatures, with molybdenum and vanadium enhancing material stability.

Oil and Mining Machinery

• Typical Applications: Drill bits, sucker rods, hydraulic props.

• Reason: Corrosion resistance and fatigue resistance make it suitable for harsh working conditions.
