42CrMo4 Heavy Duty Steel Forging Blank for Port Crane Wheels
The 42CrMo4 heavy duty steel forging blank is specially engineered for port crane wheels, where extreme load-bearing capacity, repeated impact resistance, and dimensional durability are critical.
Forged from 42CrMo4 alloy steel—a chromium-molybdenum high-strength material —this blank undergoes open die forging and heat treatment to achieve excellent toughness, wear resistance, and fatigue strength, making it ideal for heavy-duty trolley wheels, traveling wheels, and lifting mechanisms operating in port terminals and shipyards.
