This is the most common material for general-purpose hydraulic piston rods. CK45 carbon steel offers good mechanical properties, excellent machinability, and is cost-effective. It's suitable for most industrial hydraulic applications where corrosion isn't extreme.

 

Alloy steels provide higher strength and better toughness compared to plain carbon steel. They're ideal for high-pressure applications and heavy-duty machinery where higher mechanical performance is required.

 

Stainless steel piston rods offer excellent corrosion resistance, making them the best choice for:

- Marine and offshore applications

- Food processing industries

- Chemical processing plants

- High humidity or corrosive environments

 

The main downside is higher cost compared to carbon steel.

 

Quenching and tempering heat treatment improves the mechanical properties of the steel, increasing strength and toughness. This treatment is recommended for heavy-duty applications where higher mechanical performance is needed.

 

Choosing the right material depends on your application environment, pressure requirements, and budget. If you're unsure which material is best for your project, contact Xinluo Hydraulic — our engineers can recommend the optimal material specification based on your requirements.
