Forged Steel Block For Hydraulic Cylinder Base Components

Forged Steel Block for Hydraulic Cylinder Base Components

The forged steel block for hydraulic cylinder base components is a critical structural part used in the foundation of hydraulic systems. It serves as the main support for the cylinder body, ensuring stability and strength during high-pressure operations. Produced through precision open-die forging, each block features a dense, uniform grain flow and superior internal quality. Subsequent quenching and tempering heat treatment further enhances its mechanical properties, providing excellent strength, impact resistance, and durability. With high dimensional accuracy and superior metallurgical integrity, these forged steel blocks are ideal for heavy-duty applications requiring consistent performance under dynamic loads.

Product Features

Manufactured from high-quality materials such as 42CrMo, 45#, or equivalent alloy steels.

Free forged for compact internal structure and enhanced strength.

Heat treated (quenched and tempered) to achieve uniform hardness and improved fatigue resistance.

Excellent machinability and dimensional precision, suitable for complex CNC finishing.

High load-bearing capacity and outstanding resistance to pressure, shock, and wear.

Fully traceable production process in compliance with ISO standards.

Application Fields

Widely used in hydraulic cylinders as base blocks, end caps, or mounting bases.

Essential for construction machinery, mining equipment, port cranes, and metallurgical presses.

Suitable for industrial hydraulic systems, heavy mechanical actuators, and energy sector equipment.

Designed for demanding applications requiring high strength, stability, and long service life.

Steel Forgings Manufacturing Process:

Material receipt and verification → careful unloading and storage → initial surface and size inspection → controlled preheating to forging temperature → precision open-die or closed-die forging → heat treatment (quenching and tempering) for optimal mechanical properties → intermediate quality assessment → rough machining as required → non-destructive testing (NDT) for internal integrity → final dimensional inspection → protective packaging → shipment to customer.

Frequently Asked Questions (FAQs)

1. What weight range can your forged components cover?
   We produce forged parts ranging from 100 kg up to 7,000 kg, catering to medium and large industrial applications with strict quality and dimensional standards.
