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.
