We can customize various forged hydraulic cylinder tubes according to your drawings and performance requirements.
We will perform rough turning according to the customer’s drawings. All forged hydraulic cylinder tubes are delivered with reasonable rough turning allowance. This greatly reduces the time and cost of subsequent machining.
After machining, we will perform UT non-destructive testing on all forged hydraulic cylinder tubes. We will perform the next step of quenching and tempering on the forged hydraulic cylinder tubes that pass the UT test.
After quenching and tempering, the mechanical properties of our hydraulic cylinder forgings are greatly improved. For example, the tensile strength and yield strength are increased.
We have rich experience in providing hydraulic cylinder forgings of various types and sizes. If you need hydraulic cylinder forgings, please contact us immediately.

The strength of 4140 steel forgings belongs to high-strength alloy steel forgings, with high yield strength and high tensile strength.
After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
4140 steel forgings have good strength and endurance performance at high temperatures.
Our steel forgings are widely used in wind power industry, chemical industry, machinery industry, automotive industry, marine industry, power plant industry, metallurgy industry, mining industry, petrochemical industry and other industries.
