42CrMo 42CrNiMo Forged Cylinder Blocks Rough Machining for Heavy Equipment

42CrMo 42CrNiMo Forged Cylinder Blocks Rough Machining for Heavy Equipment

We manufacture high-performance forged cylinder blocks using premium 42CrMo and 42CrNiMo alloy steels, ideal for heavy equipment applications. Each forging undergoes precise CNC rough machining to ensure dimensional consistency, structural integrity, and optimal performance in demanding industrial environments. Our components are engineered for durability, impact resistance, and excellent machinability, making them suitable for use in construction machinery, mining equipment, and large mechanical systems.

Backed by 25 years of forging expertise and ISO-certified processes, we deliver custom solutions with reliable quality and fast lead times.

Our cylinder block forgings are engineered for use in high-pressure petroleum machinery such as mud pumps, fracturing units, and drilling equipment. These components are manufactured through high-quality open-die or closed-die forging processes to ensure exceptional strength, durability, and fatigue resistance under extreme working conditions.

Forged steel cylinder blocks find applications in various industries due to their strength, durability, and customizability. Their versatility allows customization for specific applications. Some common uses are:

High-Pressure Vessels:Forged cylinders are often employed in high-pressure vessels such as hydrogenation reactors, nuclear reactor pressure vessels, and nuclear power evaporators. Their robustness makes them suitable for containing pressurized substances.

Oil and Gas Pipelines: Forged cylinders are used in oil and gas pipelines. Their strength ensures reliable performance even in harsh environments.

Metalworking and Machinery: Forged steel blocks serve as bases for machinery, supports, and in precision machining processes. Their stability and load-bearing capacity make them ideal for industrial equipment.

Construction: As foundational blocks, forged steel cylinders are used for weights or structural components. They contribute to the stability and integrity of structures.

Other Industries: Forged blocks are essential raw materials in various sectors, including chemical, electric motor manufacturing, food processing, machining, and steel mills.
