Case Study: Stainless Steel Hydraulic Cylinders in Port Operations
In a busy coastal port in Singapore, a client needed to improve the reliability of their container handling equipment exposed to constant salt spray and high humidity.
We supplied our stainless steel hydraulic cylinders, specifically the Reach Stacker Telescopic Cylinder, crafted from 316 stainless steel with a 25 MPa pressure rating.
This corrosion-resistant solution replaced their standard cylinders, which frequently failed due to rust, significantly enhancing the port’s operational efficiency.
Material Comparison: Stainless Steel vs Carbon Steel for Hydraulic Cylinders
| Material | Corrosion Resistance | Typical Applications | Relative Cost | Common Issues |
|---|---|---|---|---|
| 304 Stainless Steel | High – resists oxidation and general corrosion in most environments | Food and beverage processing, light-duty marine environments, humid production lines | Medium | Susceptible to pitting corrosion in chloride-rich or saltwater environments |
| 316 Stainless Steel | Extremely high – offers superior resistance to pitting, crevice, and chemical corrosion | Pharmaceutical plants, offshore/marine platforms, chemical processing, cleanrooms, medical equipment | High | Higher material and machining costs, but better long-term performance in aggressive environments |
| 316L Stainless Steel | Similar to 316 but with lower carbon content – enhanced weldability and corrosion resistance | High-purity systems, biotech, nuclear, ultra-clean processing lines | High | Slightly lower mechanical strength compared to standard 316 |
| Carbon Steel | Low – prone to rust and oxidation without surface treatments | Dry indoor environments, general industrial use, cost-sensitive hydraulic applications | Low | Requires coatings or plating; not suitable for corrosive or hygienic environments |
???? Professional Insights:
-
Why 316 is Superior for Corrosive Environments:
316 stainless steel contains molybdenum, which enhances its resistance to chlorides and harsh chemicals — making it ideal for marine and pharmaceutical applications. -
When 304 is Sufficient:
304 stainless steel is often adequate for food processing or humid indoor conditions, offering a good balance of corrosion resistance and cost. -
Carbon Steel Limitations:
Although carbon steel offers strong mechanical properties and is economical, it corrodes rapidly without protective coatings, making it a poor choice for wet, corrosive, or hygienic environments. -
Weldability & Fabrication Considerations:
316L stainless steel, with reduced carbon content, is preferred for applications requiring frequent welding, as it reduces the risk of intergranular corrosion after welding.
✅ Tips for Buyers:
-
Choose 316/316L for maximum durability in critical or corrosive environments.
-
Choose 304 for moderate corrosion resistance in cost-sensitive hygienic settings.
-
Avoid carbon steel unless the application is dry, controlled, and corrosion exposure is minimal
