    42CrMo4 Large Diameter Rough Machined Heavy Steel Forgings for Hydraulic Cylinders

    42CrMo4 Large Diameter Rough Machined Heavy Steel Forgings for Hydraulic Cylinders. Our 42CrMo4 large diameter heavy steel forgings are precision forged to meet the demanding strength and performance requirements of hydraulic cylinder components in heavy-duty industrial applications. Manufactured using high-quality 42CrMo4 alloy steel, these parts offer excellent toughness, wear resistance, and fatigue strength—making them ideal for use in harsh, high-pressure environments.


    Each forging is rough machined according to customer specifications, with consistent dimensional accuracy and surface integrity. We supply forgings in weights ranging from 100 kg to 7000 kg, suitable for both small batch and bulk production needs.


    Whether you require a custom forging for OEM use or replacement parts for hydraulic systems, our ISO-certified factory ensures reliable quality and on-time delivery.
