Performance Requirements

Commonly used materials:
4140/EN19/42CrMo4: It has high strength and good wear resistance, which can meet the requirements of heavy load and wear resistance, suitable for gears of cranes and other equipment.
20CrNi2Mo: After carburizing, its surface is wear-resistant, and the core has strong impact resistance, suitable for gears in gearboxes that bear complex loads.

Material Heat Treatment Key Characteristics Typical Applications
4140 / EN19 / 42CrMo4 Quenching and Tempering High strength, good wear resistance, meets heavy load and wear resistance requirements Gears for cranes and other heavy equipment
20CrNi2Mo Carburizing Wear-resistant surface, strong impact-resistant core Gears in gearboxes bearing complex loads
