| High Light | Alloy Steel Forgings Crane Wheel ，Crane Wheel 42CrMo ，Port Machinery Open Die Forging | ||
Alloy steel forgings 42CrMo open die forging for Port machinery and lifting equipment. Our 42CrMo alloy steel open die forgings are engineered for high-performance applications in port machinery and lifting equipment. Produced through precision open die forging, these components offer excellent strength, toughness, and fatigue resistance, ensuring reliable operation under heavy loads and harsh working conditions.
The 42CrMo material, known for its superior hardenability and mechanical properties, is widely used in critical structural parts such as forged gear shafts, crane wheels, lifting hooks, and load-bearing components. Each forging undergoes strict heat treatment and non-destructive testing to guarantee internal soundness and dimensional accuracy.
